I have an idea in its very early stages and I’m looking for a skilled professional who can help turn that concept into a concrete, working solution. The exact medium—whether web-based, mobile, graphics-driven, or something hybrid—hasn’t been locked down yet, so I value a flexible mindset and a consultative approach. Here’s what I need right now: • An initial discovery session to clarify goals, end-users, and technical constraints. • A concise roadmap or specification document that outlines recommended technologies, milestones, and rough timelines. • A first proof-of-concept or visual prototype that demonstrates the core idea and gives us a tangible asset to review together. If you have a track record of taking loosely defined projects fro...
I have an APK that I finished coding but have not been able to run through real-world checks because my current device is outdated. I need solid, actionable feedback on its overall performance when installed on modern Android smartphones. Here is what I expect from you: • Install the APK on at least one recent, mainstream smartphone model. • Use it as an everyday user would for a short session, paying attention to loading times, responsiveness, and any lag during navigation or feature use. • Note temperature spikes, frame drops, or crashes if they occur, and capture logs or screen recordings where helpful. • Summarise your findings in a concise report, highlighting any critical issues first and suggesting optimisation ideas where obvious.

Project Title: React Developer Needed for Web App MVP Tweaks & Voice API Fix Project Description: I have a functioning Minimum Viable Product (MVP) web application that was generated using a low-code AI builder. The complete source code has been exported and is safely stored in a GitHub repository. I need an experienced frontend developer to take over the codebase, fix a specific microphone timeout bug, make a few minor UI adjustments, and deploy the updated code. Core Tasks: 1. Fix Voice Recording Timeout: The app uses a voice-to-text recording component. Currently, it cuts off the user after 15-20 words (likely an aggressive VAD / Silence Timeout issue or the API not being set to continuous listening). I need this modified so the microphone stays open for up to 3-5 minutes, allowing ...
I need a clean, fast, high-conversion WordPress website for a Sydney 24/7 emergency electrician lead generation service (we capture calls & forms and route/sell them to licensed partner electricians — we do no jobs ourselves).

I’m putting together a fresh, modern UI for a water-delivery service and I need the complete flow mapped in Figma for both iOS and Android. The goal is to hand developers a clickable prototype that already answers every usability question, so screens, components and states all have to be clearly laid out and named. The product experience should cover: • A smooth user onboarding flow with login and registration • Real-time order tracking that feels intuitive on any screen size • A secure, well-integrated payment gateway • Separate, fully featured log-ins for multiple vendors so suppliers can manage their own orders Please build the design around contemporary mobile patterns—clean typography, generous whitespace, restrained color accents—and keep...
I’m building a fully-customised e-commerce mobile application inspired by Flipkart and need it delivered for both iOS and Android. The end product must feel enterprise-grade from day one, yet remain flexible enough for rapid feature additions as the business scales. Core functionality I must see at launch: • Shopping cart that supports coupons and dynamic pricing • User reviews with ratings, photos, and moderation tools • Secure payment-gateway integration for cards, UPI, wallets, and COD Beyond these essentials, expect everything from intuitive search and smart recommendations to an admin dashboard and robust analytics. Clean, modular code, strong attention to UI/UX, and adherence to App Store and Play Store guidelines are non-negotiable. How to win the con...
I run an educational mobile application that is already live on both Android and iOS. I’m looking for a seasoned full-stack developer who can jump straight into the codebase, roll out new features, and then stay on as the go-to person for annual maintenance, performance tuning, and bug fixing. You will be touching the entire stack—mobile front-end for Android and iOS as well as the server side and database layer—so confidence switching between platforms, APIs, and deployment pipelines is essential. When you reply, focus on your relevant experience. I’d like to see where you’ve shipped cross-platform features, kept apps healthy post-launch, and managed long-term maintenance for a live product. Code samples or links to production apps will help me assess fit q...
Description: We are building a sports performance mobile app and need a custom human body illustration (front & back) prepared as an interactive SVG with clickable zones. IMPORTANT: This is NOT just a visual illustration — it must be structured for development (each body part must be a separate clickable element). What we need: * 1x front body view * 1x back body view * Delivered as: * SVG (required) * EPS (optional) * Source file (Figma or Illustrator preferred) Key requirement: Each body part must be a separate vector shape with a unique ID. Example IDs: * left_achilles * right_heel * left_sole * right_toes * lower_back * left_knee_front We will use this in a mobile app where users tap body parts to report pain. Body zones: Upper body (simple): * head * neck *...
I’m ready to launch a colour-prediction game that runs flawlessly in mobile browsers, and I need a developer who can take it from concept to live site. The core idea is simple: players land on a clean, modern interface, choose a colour they believe will appear next, and immediately see whether they’ve won. While the gameplay is straightforward, the presentation must feel sleek, fast, and polished on every handset. Here’s what I expect you to handle: • Responsive, mobile-first front-end built around a modern and minimalist aesthetic—smooth animations, intuitive touch controls, and zero clutter. • Back-end logic that handles real-time colour generation, result validation, and basic player session tracking. • Lightweight admin panel (or clear hooks ...
Project Title: Expert Flutter & Firebase Developer Needed for Mobile & Desktop Society App (Single Codebase) ​About the Project: We are looking for an experienced Flutter & Firebase developer to build a highly secure, professional-grade application for "Sri Ramabandhana Mutual Aid Society" (SRMAS). The application will handle complex financial ledgers, multi-tier approvals, and member management. We require both Mobile (Android APK) and Desktop application versions. Since Flutter supports multi-platform development, we expect a single codebase that works seamlessly across both platforms. ​Tech Stack Required: ​Frontend: Flutter (Single Codebase for Mobile Android APK & Desktop) ​Backend: Firebase (Firestore, Phone Auth, Cloud Functions, Cloud Scheduler) ​1. Core A...
I want a complete Android-only social networking app built from the ground up and, just as important, I want to understand every step that goes into creating it. Your role will be two-fold: first, deliver a fully functional APK (plus clean, well-commented source code); second, walk me through your architecture, toolchain, and deployment process so I can replicate or extend the project later. Core expectations • Native Android build (Kotlin or Java with Android Studio). • Standard social features—user registration/login, profile editing, posts with images/video, likes/comments, and real-time notifications. • Secure back-end (Firebase, Supabase, or a lightweight REST API with SQL) and cloud storage for media. • Clear documentation: project setup, key code s...
I need you to visit active rice-growing areas across Liberia and Guinea, stand on each farm, and record an accurate GPS point. Every point you collect will eventually feed into an agronomic mapping project, so positional accuracy matters: please rely on a handheld GPS receiver or a smartphone app that can export KML with at least 5 m precision. Once you finish a day in the field, save the coordinates directly to KML. All points should carry a short, clear label—farm name or a local reference is fine—so I can later match them with my own database. If you can easily capture extra details such as farm size, owner name, or rice variety, feel free to include them as extended attributes in the KML, but my core requirement is the position itself. The work is entirely on-site; satell...
I'm looking for an experienced game developer to refine and enhance the gameplay mechanics of my existing VR and cross-platform game. The primary focus will be on improving the game rules and logic. Key areas to address include: - Refining and redefining game workings and rules Ideal Skills and Experience: - Strong background in game development, particularly in VR and cross-platform environments - Expertise in game mechanics, rules, and logic - Proficiency in gameplay programming and design - Ability to collaborate and communicate effectively throughout the development process If you have a passion for creating immersive and engaging gameplay experiences and possess the technical skills to bring my vision to life, I would love to hear from you.
I need an automated chatbot that can handle customer support queries directly inside our existing mobile app. The bot should greet users, understand common questions about our services, and deliver accurate, friendly responses without human intervention. Where answers fall outside its knowledge base, it must smoothly escalate to our live support queue so no conversation is ever dropped. Key deliverables: • Dialog flow design covering all current FAQs, account issues, and order-status checks • Natural-language understanding setup (Dialogflow, IBM Watson, or similar) with intent and entity training • Seamless SDK integration for both iOS and Android versions of the app • Simple admin panel or JSON file for my team to update responses without code changes • H...
I need a mobile application that spotlights the nightlife scene across ten different urban cities. The app’s single, crucial focus is a polished venue-profile section: each profile must display a concise venue description alongside accurate opening hours. Everything else—from navigation flow to visual style—should revolve around making these profiles quick to discover and pleasant to read. You are free to recommend the tech stack and architecture, but I do expect clean, well-documented code, straightforward deployment instructions, and a user-ready build for both major mobile platforms once development is complete. If this first release hits the mark, I will consider adding extra modules later (for instance, event listings or user reviews), so structuring the projec...
I want to launch a dedicated Android social media app and need it developed from the ground up. The platform is Android only, so please focus on the latest Android SDK while keeping compatibility back to at least Android 8. I already have wireframes that outline a familiar social feed: users create profiles, follow one another, post photos or short videos, like, comment, and receive push notifications. Your role is to refine the UI to Material Design standards, build the front-end in Kotlin or Java, and connect everything to a scalable cloud back-end—Firebase is my first thought, but I’m open to an alternative you can justify. Robust authentication, real-time data sync, and basic content moderation hooks are essential. Performance, security, and clean, well-commented code will...
I’m extending our engineering team on a long-term software development project that targets both iOS and Android. The job is hands-on coding: committing well-structured, tested features to our Git repo, reviewing pull requests, and gradually tackling more complex tickets as you grow with us. I’m specifically seeking a beginner to mid-level developer who (1) currently resides in the United States and (2) identifies as female. I want to invest time in mentoring someone reliable, curious, and ready to stick with the project for the long haul. The current stack is Swift and Kotlin with a RESTful back end. Familiarity with React Native, Flutter, or similar cross-platform tools is welcome but not mandatory—what matters most is clean code, steady communication, and a learning ...
We're an app & web development studio based in Miami, FL and we're looking for a cross-platform Flutter developer who has all the equipment needed to produce end-to-end apps for iOS and Android. Because iOS distribution is a must, you will need reliable access to a Mac and an iPhone for building, signing, and TestFlight testing. Our focus is mostly fitness but we do develop other kinds of apps as well. Keep in mind that the main requirement for this job position is communication, organization, professionalism and ability to organize a project well + follow rules and instructions 100% of the time. Only apply if you have previous experience working in a team environment and you will be a complete team player. Work hours are US EAST COAST TIME so make sure you understand ...
I'm looking for an experienced mobile app developer to create a social networking app for Android.

I’m ready to translate a fresh concept into a polished, production-ready Android application. The single most important piece of this build is a seamless, secure in-app purchase experience powered by Google Play Billing, allowing users to buy and restore premium features or content inside the app. No account system or push notifications are needed for the first release; the emphasis is on clean UI, solid Kotlin/Jetpack architecture, and bullet-proof purchase handling for consumables, non-consumables, and—if practical—subscriptions. I will share wireframes, artwork, and detailed user flows as soon as we kick off. If you have suggestions on payment flow optimisations, crash-free implementation patterns, or store listing compliance, feel free to bring them forward. Deliver...
I need a native-quality Android application that mirrors the core experience of my existing video-streaming website while adding mobile-first polish. The app must let viewers sign up, log in, and manage their own profiles, and it also has to give approved creators the ability to upload and share videos directly from the phone. Access to the catalog will be subscription-based, so the flow for choosing a plan, paying, and renewing has to feel seamless. We are onboarding a new Indian payment gateway (full REST API documentation is ready on my side) and I want that integration handled end-to-end—plan creation, recurring charges, webhook handling, and graceful failure states included. I am aiming for the standard streaming comforts: smooth adaptive playback, background audio, and se...
We are looking to hire experienced freelancers to help build a next-generation AI-powered camera management system for a camera business that is moving from traditional operations to a more advanced, centralized, and intelligent platform. The objective is to develop a scalable solution that can support multi-camera monitoring, AI-based body scanning, behavior tracking, vehicle number plate recognition, drone integrations, real-time alerts, and secure admin control. The platform should be designed for future growth and long-term operational use. This is not a basic prototype — we are looking for professionals who have worked on relevant, production-level systems. Project Scope The system will include, but is not limited to, the following capabilities: 1. Live camera streaming and re...

I would like to build an application that has a very similar interface as whats app to allow customers to place orders based on real time stock available. Currently customers place orders via whats app and have made it clear they do not want to switch to a website but may be open to trying an app for orders if it is very simple. We want to move away from whats app as we manually log orders from whats app chats and due to the volume and difference in the orders, we tend to have human error while logging orders. The app is for fresh produce (vegetables, fruit, mushrooms, herbs etc). Currently we have 20sku's but want to add more (wont be more than 40 total sku's). The idea is to have as much simplicity as possible as the customers tend to be older persons who are not as tech savy...

I want to build a mobile app called Helping Hand Pension using Flutter (Android first). The app will include OTP-based login, a dashboard (balance, pension estimate, next payment), deposit system (fixed + custom amounts), and UPI payment integration (PhonePe, GPay, Paytm). It should have a savings screen (contributions + graph), pension calculator, notifications, and user profile with document upload. An admin panel is required to manage users, track payments, add bonuses, and export data (Excel). Preferred backend: Firebase or Node.js. UI should be clean, minimal, and modern (similar to CRED/Blinkit). Looking for a reliable developer for long-term collaboration.
I’m planning a fully fledged Battle-Royale game for both iOS and Android and need an experienced mobile developer or team to turn the concept into a polished, scalable app. The core loop is classic last-player-standing, but I want it to feel modern, visually striking and ready for live-ops from day one. Key gameplay and monetisation features I must see at launch: • Mehrspieler-Modus with smooth matchmaking and low-latency real-time play • Anpassbare Charaktere, including skins and cosmetic load-outs saved to the player profile • In-Game-Käufe integrated with Apple & Google billing, supporting consumables and cosmetics The art direction leans toward a realistic style—think detailed environments, believable lighting and fluid character animation&...
Dating Application like tinder, truly madly
I’m planning to build a mobile productivity tool focused solely on task management and to release it simultaneously on iOS and Android. The first milestone is a clean, intuitive interface that lets users create, prioritise, and track tasks, with push-notification reminders and offline access that syncs when a connection returns. Calendar integration and broader collaboration tools can wait for later versions; right now I want a rock-solid core experience. End-to-end delivery is essential. That means UX research, wireframes, polished UI that follows each platform’s design language, the complete codebase (Swift/Kotlin or a high-quality framework such as Flutter or React Native), an API layer if you decide server sync is best, and fully tested release builds ready for the App Sto...
I’m building a modern, Spare-Room–style marketplace where landlords and tenants can connect effortlessly on iOS, Android, and the web. Before a single line of code ships, I need a polished, modern-and-trendy UI/UX that feels instantly familiar to everyday renters yet powerful enough for professional hosts. Core features to be designed and built: • User profiles for both landlords and tenants • Robust search and filtering for available properties, including city or specific-quarter targeting • In-app messaging so parties negotiate without leaving the platform • Transparent pricing display plus optional “Top Listing” adverts to boost visibility • Landlord verification workflow to maintain trust and safety • Comprehensive admi...
I need a top-tier engineer to build a private mobile-API sniper able to claim 2- and 3-letter Instagram usernames faster than anyone else. The solution has to run against both Android and iOS endpoints and must never touch browser automation. Here is the performance bar I expect: the service should comfortably sustain more than 1,000 requests per second while keeping end-to-end latency below 50 ms. To achieve that you may architect a multi-threaded runner, spin up geographically distributed workers, or use any other creative optimisation—so long as the target numbers are met in real-world tests. Signature encryption, device fingerprinting, and the dreaded 429 rate limits all need to be bypassed with a custom-built approach rather than off-the-shelf libraries. Once a username is sec...
I’m commissioning a FlutterFlow application for simultaneous release on the Play Store and the App Store. The product centres on streaming and downloading audio content, backed by Firebase services, and needs to be ready within 4–5 weeks. Scope of work • Configure Firebase Auth and Firestore so user data and content lists stay in sync across platforms. • Build an in-app audio player with background playback, seek, and offline caching. • Embed a PDF viewer and video playback screen for supplementary material. • Create a secure, server-side access-code mechanism that unlocks premium sections after validation. • Prepare, test, and hand over production-ready Android (.aab) and iOS (.ipa) builds plus the full FlutterFlow project. Please send a fi...
My Android app is finished, thoroughly tested, and the signed AAB is waiting in a folder—what’s left is the actual submission. I’m familiar with Play Store policies, so I don’t need compliance coaching; I simply want the app uploaded and released through the Google Play Console. Deliverables • Upload the provided AAB to the production track • Complete all mandatory console forms using the text, screenshots, and privacy-policy URL I supply • Address any immediate warnings or errors raised during the submission flow • Provide a brief hand-over report once the console shows the status as “Published” (or detail outstanding actions if Google flags something) Ready to begin immediately
I need a lean, battery-friendly Android app that can stream a smartphone’s GPS coordinates in real time. Once the user grants permission, the app should run as a foreground service, capture accurate latitude and longitude, and post them every few seconds to the REST endpoint I will provide. A small in-app Google Maps view must mirror the live position so we can confirm everything instantly. Please follow current Android 13 location-permission rules and make sure tracking survives reboots, Doze, and other battery optimisations. I will share the API spec; you may use Retrofit, Volley, or any modern HTTP client you prefer, as long as JSON payloads stay lightweight. Deliverables • Complete Android Studio project (Kotlin or Java) with well-commented code • Signed release A...
