I’m ready to commission a complete Android-only utility application whose core purpose is secure, real-time messaging. I already have the concept and basic workflow sketched out; what I need now is an experienced mobile developer who can turn those ideas into a polished, production-ready APK and guide it through Play Store submission. Here’s the scope in plain terms: • Build a native Android app that opens quickly, registers users by phone or email, and lets them exchange text, images, and voice notes in one-to-one or small-group chats. • Implement end-to-end encryption with a well-maintained library (for example, Signal protocol or similar) so all conversations stay private by default. • Design a clean Material-you inspired UI; I have colour references and a s...

I’m expanding my online course-counselling platform with a dedicated AI engine that pinpoints the right colleges for each student. The tool’s single, non-negotiable goal is to return a list of institutions that actually offer the course a learner wants. When a user specifies a field of study the system must instantly sift through my database and surface matching undergraduate, postgraduate, and doctoral programmes. Because course availability is the guiding criterion, the model should rank or filter results based on how comprehensively each college covers that subject area. I’d like the code structured so I can add extra filters later—location and tuition, for example—without rewriting the core logic. A conversational interface (chat or natural-language sear...

I have already written most of a custom ERP/CRM in Python, but a handful of features and polish tasks are still unfinished and blocking release. The core database schema, main views, and API endpoints are working; what I now need is a developer who can read my existing codebase quickly, identify the gaps, and deliver fully working, production-ready modules. The outstanding items include completing some accounting, inventory, and customer-facing workflows, closing any authentication loopholes, squashing bugs that surface during integration tests, and making sure the system produces clean, exportable reports. You will have access to my current Git repository, schema documentation, and a short list of known issues to start with—beyond that, I’m happy to walk you through the busin...

I have a growing pipeline of AI-driven products that need to move from idea to production over the coming year. Every project centres on developing brand-new applications, so I’m looking for engineers who can own the full lifecycle: turning raw data into a reliable, cloud-hosted model and keeping it healthy in the wild. The work spans three core domains—Natural Language Processing, Computer Vision, and Predictive Analytics—and typically involves: • Data preprocessing and cleaning • Model development and training (Python, TensorFlow or PyTorch preferred) • Containerised deployment and continuous monitoring (Docker/Kubernetes, AWS or GCP) You’ll step into projects such as conversational agents, visual quality-inspection tools, and forecasting eng...

I need a small Python-based utility that runs reliably on macOS and strips the SyntID watermark Google bakes into both its Text-to-Music and Text-to-Speech outputs. The goal is simple: after processing, the resulting audio should pass Google’s own detection checks while sounding identical to the human ear. Here’s what matters most to me: • macOS compatibility out of the box (Monterey and newer) using standard Python 3 libraries plus any open-source audio packages you feel are essential. • One command (or callable function) that accepts a Google-generated audio file, cleans it, and writes back a high-fidelity file in the same format. • Clear inline comments and a concise README so I can understand the logic, install any dependencies with Homebrew/pip, and r...

I’m giving the in-game interface of my browser-based idle game a full visual makeover and want it to scream retro pixel-art. The underlying logic is finished; all I need now is an eye-catching reskin. You’ll work directly in the existing Java back end and React/HTML front end, refactoring only the visual layer—layouts, components, sprites, colours, fonts, animations—while keeping every hook, state and API call intact. The Sprites and the UI-Elements are already existing and was created by me. Here’s what I’m after: • A cohesive pixel-art look inspired by classic arcade screens—bold palettes, chunky fonts, sharp contrast. • Clean React components and CSS that make future tweaks painless (feel free to vibe-code small utility components...

I have an e-commerce concept and want it transformed into a polished Android mobile app that feels both stylish and intuitive. Core objectives • Build a native Android application focused on product browsing, secure checkout, and order tracking. • Craft an interface that looks clean, modern, and unmistakably premium—smooth animations, thoughtful spacing, and consistent typography are essential. • Integrate fundamental e-commerce features: searchable catalog, product variations, shopping cart, wish-list, multiple payment gateways, and push notifications for promotions and shipping updates. Technical expectations • Develop in Kotlin (preferred) or Java, following current Android best practices. • Use a scalable architecture (MVVM or similar), wi...

Project Description: We are looking for a reliable freelancer based in Bangladesh to support an ongoing project involving procurement and setup of Robi prepaid SIM cards.

I need an application that reads a multipage PDF, pulls out all the text, and then pours that content into a fresh one-page PDF that follows a custom layout I already designed. The flow is simple: open PDF → extract every text element in reading order → map each string to its assigned field or zone in my supplied template → generate a brand-new single-page PDF ready for distribution. My design file shows exact font sizes, margins, headers, and footers, so the app must respect those specifications pixel-for-pixel. Dynamic text should auto-shrink only when a block overruns its allotted space; everything else should remain fixed. No images or tables need processing—pure text only. I’m open to your preferred stack (Python with PyPDF2/PDFPlumber, Java with PDFBox, o...

I’m looking for an experienced ethical hacker who can also roll up their sleeves and work directly on the codebase. Your first priority will be to probe our existing applications and utilities for security weaknesses, then patch or refactor the vulnerable components yourself. You will work from user stories and specs that I provide, translating them into secure, efficient software. Day-to-day you’ll be analysing requirements, recommending upgrades, collaborating with the rest of the dev team, and documenting everything—from flowcharts and user guides to the exact remediation steps you take. Routine maintenance and performance tuning are part of the remit as well. A solid command of Java and Python is essential, and you should feel at home in relational databases lik...

I need a very small, self-contained prototype that shows how you would structure an “apple fruits records” application. At this stage I am deliberately keeping the brief minimal because the goal is to evaluate your approach, code quality, and communication style before we move on to a full build. Here is what the first milestone should demonstrate: • A clean data model able to store individual apple entries (feel free to invent a few sample fields such as variety, harvest date, or quality score so I can see relational thinking). • A simple screen that lists the saved records and lets me add a new one. • Clear, commented source code plus a short read-me describing the architecture and any third-party packages you introduced. Platform is flexible—use th...

I’m ready to launch a clean, fast personal blog and need a developer who can take it from blank repo to live site. The stack can stay lightweight—HTML5, CSS3, and vanilla JavaScript on the front end, with PHP (or Java if you prefer) handling any server-side logic. We’ll work in VS Code so everything stays transparent and easy to review. Core requirement: a working comment section that lets readers leave, edit, and delete their own thoughts while protecting the site from spam. I’m open to adding extras such as social media hooks or a search bar later, but for this first milestone the focus is the blog itself and the comment workflow. Deliverables • Fully responsive blog template with home page, post page, and error page • Comment system (CRUD operatio...

I am building an AI-driven chat bot whose core job is health monitoring for both patients and healthcare providers. The conversation layer needs to track vital-sign data, send timely medication reminders, and walk users through symptom checking in plain language. Think of it as a virtual nurse that can interpret readings from connected devices, flag anomalies, and escalate critical results to clinicians while also giving patients easy-to-follow guidance. You will take the lead on: • Designing conversational flows that capture vitals (blood pressure, heart rate, SpO₂, glucose, etc.) and respond intelligently to out-of-range values. • Implementing medication reminder logic with flexible scheduling, snooze, and confirmation that doses were taken. • Building a symptom-che...

I need support with custom ABAP development focused solely on building ALV Reports inside our S/4 HANA system. The functional specs are ready; what I’m missing is a clean, well-structured program that: • pulls data from both standard and custom tables, • follows best practice performance techniques (field symbols, hashed tables, proper buffering), • presents the output in an interactive ALV grid with sorting, filtering, subtotaling and user-specific layouts, and • comes with inline documentation and basic test data so I can run it immediately after transport. All coding must comply with SAP naming conventions, be fully transportable, and avoid obsolete statements. I work with Eclipse ADT and SE80, so please develop in a way that runs flawlessly in either e...

I need twelve Android users to help me measure how my app affects battery life during heavy, real-world use over a 14-day window.

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 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 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...

I want to create a brand-new programming language, purpose-built for full-stack web development. Think of the expressive ease of Python blended with the modern, modular feel of Kotlin—yet tailored from the ground up for today’s browser and server demands. Here is what I need from you: • A clear language specification that covers syntax, type system, standard library scope, and concurrency model. • A working reference implementation (compiler or interpreter) able to run real code on both client and server. If you choose to compile to JavaScript for the browser and target, say, a lightweight VM or Node.js on the back end, that works for me as long as the developer experience stays seamless. • Core tooling: lexer/parser, REPL, package manager basics, and a min...

I want to build a custom large-language model that goes beyond text-only chat. The goal is a predictive engine that can read free-form text, combine it with numerical features, and return forward-looking insights. In practice that means designing an architecture able to embed and fuse both modalities, training it on my mixed dataset, and validating that the model can reliably forecast the target variables we care about. You will take me from data preprocessing through to an inference-ready checkpoint. I expect clean Python code (PyTorch or TensorFlow), sensible use of the Transformers or similar libraries, and a clear explanation of why each modelling choice was made. Please include evaluation notebooks that show the lift over conventional baselines and provide an API-style script so I ca...
