I want to build a stake api code claimer

I’m building a new web-based product and need an experienced developer to take ownership of the API layer. The immediate goal is to design and implement a clean, well-documented interface that my front-end team can consume without friction.

You’ll help me weigh those options, outline the data models, and then write production-ready code with unit tests. If you prefer frameworks like , FastAPI, Laravel, or Django Rest Framework, let me know; I’m open to recommendations as long as the final sol...

Full-Stack SaaS Developer Needed for Multi-Tenant Digital Catalog Platform

Our job portal’s search results page is being dragged down by slow data retrieval, and it’s directly affecting the overall speed and load time of the site. I need someone who can dive in, pinpoint the bottlenecks, and deliver measurable gains without disrupting existing features. Here’s how I see the engagement: • Analyse current queries, API calls, and any middleware that sits between the database and the front-end to uncover why the data feed to the search results is sluggish. • Optimise what you find—whether that means rewriting SQL, adding smart indexing, implementing server-side caching, or fine-tuning backend code. • Validate improvements with before-and-after metrics: Time To First Byte, total page load, and server response time for typic...

I’m ready to launch a full-scale food delivery platform built with React on the front end, Spring Boot for the API layer, and MySQL underneath. The site must feel fast and intuitive on phones, tablets, and desktops, so thoughtful responsive design is essential. Core workflow • Customers browse restaurant menus, search or filter dishes, add items to a cart, then place and pay for an order in a few clicks. • Restaurant Owners have their own portal to update menus, prices, photos, and track incoming orders in real time. • An internal admin dashboard will let me supervise every restaurant, user, and transaction from one place. Key feature set • Secure registration / login for Customers and Restaurant Owners • Stripe (or similar) card processing plus P...

I’ll match your background against several active vacancies and, if there’s a fit, introduce you directly to the hiring teams for their streamlined inte...

Certification Program Management Platform — Partially Built, Looking to Complete I am building a web platform to manage a multi-step applicant certification process from start to finish. A solid working prototype already exists and I need an experienced developer to take it to production. The workflow: Applicant receives a unique link → completes an application → acknowledges program rights and signs digitally → uploads ID documents via desktop or mobile → takes a 199-question online exam (80% to pass, with study and retry mode) → completes an in-person assessment recorded by admin → system generates all required program documents in a single applicant file. Already built (working HTML/JS prototype): Full applicant wizard with digital signature and mo...

My store’s product pages badly need a face-lift. I want each item to load fast, feel intuitive on desktop, tablet and mobile, and guide shoppers smoothly to the cart. To get there, I need a developer who can handle both the visual overhaul and the underlying code. Here is what I expect: • Redesigned navigation on every product page so users can jump between variants, images and key details without friction. • Responsive UI/UX refinements for mobile and tablet—no elements cropped, misaligned or hidden. • Back-end tweaks or refactoring where necessary to support the new front-end structure, keep page speed high and ensure data flows correctly to the cart and checkout.

I need help solving 2 coding challenges as part of an interview process, in Javascript and nodejs

I’m putting together a full-featured, multi-page gaming provider site. The core of the project is a clean, responsive front end where visitors can register, create a profile, and immediately dive into the titles we host. Behind the scenes I’ll need a solid game-hosting and management layer so I can upload new games, tag them by genre/theme, schedule events, and switch featured titles without touching code. Structure • Separate landing, game catalogue, account dashboard, and support pages, each with its own theme so the experience feels varied and lively. • Secure user registration and profile editing (social login optional but not required at launch). • Admin console for game uploads, version control, on/off toggles, and basic analytics. Technical notes...

I’m putting together a modern, responsive application that must feel effortless on both desktop and mobile screens. My top priority is user experience and design, with intuitive navigation sitting at the very heart of the project. I still need the full stack: a clean, component-based front-end, a secure and scalable back-end, solid database integration, and well-structured APIs. Performance, security, and maintainability all matter, but only if they serve a beautiful, friction-free interface. Here’s what I need from you: • A brief overview of projects where you have owned both UI/UX and the underlying architecture. • The tech stack you propose and why you feel it fits the goal of a fast, responsive, user-driven product. • An estimated timeline that includes...

I need a small application that wraps Nmap and exposes its power through a clean, browser-based dashboard. The tool must be able to trigger full TCP, UDP and SYN scans against targets I enter, then stream or refresh the results live in the web interface so I can sort, filter and export them. I am flexible on the underlying stack—Python + Flask, Node, Go or another lightweight framework is fine as long as installation is straightforward on Windows, Linux and macOS.

Please include: • A web UI that lets me specify targets (single IP, CIDR, or list) and choose the three scan types. • Real-time...

I want to bring a new social media idea to life through a purpose-built Android application. This is a full application development project, so I need someone who can take the concept from blank screen to a polished, Play-Store-ready release. The core scope is native Android—Java or Kotlin is fine—covering everything a modern social platform needs: secure sign-up and login, user profiles, an endlessly scrolling feed, basic interactions such as likes or comments, plus real-time push notifications. If you’re comfortable setting up a lightweight backend as well (Firebase, Supabase, or another scalable option), that’s a bonus, though I’m open to your recommendations. Deliverables I expect: • Production APK ready for testing and release • Clean, wel...

I need an engineer who can wire up OneSignal push notifications end-to-end for my Lovable web app, which is wrapped as a native iOS build through Median. Users authenticate with email / password, Google, Apple and magic link; whichever method they choose, their Supabase UUID must become the external_user_id in OneSignal so that every notification targets the right person. On first launch the app should ask for all notification permissions in a single prompt, respecting Apple guidelines. From there the flow has to stay in sync with authentication: register the device on login, cleanly remove it on logout, and keep token changes in the background. I have built a custom panel in the admin backend which ties push notifications to site notifications, and also enables custom notifications to a...

My WordPress site relies on a custom Fuse.js-powered search box, but right now the results come back incomplete—some obviously relevant posts and pages never show up. The search bar itself responds, yet the list it returns is being trimmed in a way that hides content visitors need. I need someone to step in, review the existing implementation (indexing script, options such as threshold, keys, and distance) and trace why items are dropped. This might involve rebuilding the index, adjusting the weighting, or rewriting the callback that formats the results before they reach the front end. Whatever the cause, the outcome I’m after is a fully-functioning search that surfaces every relevant match. Deliverables • Clean, documented code or patch applied to my child theme / pl...

Core requirements • A fully custom back-end chat engine (Node, Laravel, Go or a comparable stack you are comfortable maintaining) with WebSocket or SSE for instant messaging, typing indicators, and read receipts. • An operator dashboard that shows active sessions, conversation history, and basic visitor metadata (referrer, browser, country, current page). • End-to-end encryption for messages at rest and in transit,...

My marketing site still relies on an old Base44-centric codebase and the build keeps failing because of those legacy dependencies. I need you to step in, track down whatever is preventing a clean build, and trim away the Base44-only parts so the project can compile and run without them.
