I’m building a brand-new web application under a fast-moving startup and I need one dedicated engineer to own the full stack from day one. We operate on California (PST) business hours, so you’ll work those hours alongside me and the design team, collaborating live through Slack, GitHub and Zoom. The core of the product is a React-driven front end, coupled with whatever back-end stack you’re most productive in—Node/Express, Python/FastAPI, or a comparable RESTful setup. You’ll start with green-field architecture decisions, set up CI/CD, wireframes to working screens, database schema, APIs, automated tests and production deployment. This is a full-time, monthly-salary role and I’m hiring an individual developer only—no agencies or teams. Automa...

I run a product-led SaaS company and need a full-stack engineer who can work the same hours I do—9 am – 5 pm Pacific Time, Monday through Friday. Every feature we ship is built with JavaScript from back to front, so daily work revolves around a Node.js/Express API layer feeding a React web application. You will own end-to-end development: refining tickets in our Monday morning grooming call, writing clean, well-tested Node services, and pushing pixel-perfect React components that match Figma specs. I deploy through a GitHub-driven CI/CD pipeline to AWS (ECS + RDS). Familiarity with GraphQL, PostgreSQL, Docker, and Jest is helpful, but solid Node.js fundamentals and modern React experience are the non-negotiables. Success is straightforward. By the end of each two-week spr...

I need an AI-driven chatbot that lives inside WhatsApp and answers everyday questions about our products and services. Its purpose is strictly general inquiries, so the experience must feel like texting a friendly teammate—concise, helpful, and casual. The bot should understand open-ended queries, remember short-term context, and share quick links, images, or short text snippets when that speeds things up. Whenever a request goes beyond its knowledge, it must hand the chat off to a human agent inside the same WhatsApp thread. I’m open to Dialogflow, Rasa, or a clean custom build on the WhatsApp Business API, provided the setup stays simple enough for my in-house dev to maintain. Deliverables • A fully functional WhatsApp chatbot hosted on a cloud platform (AWS, GCP, or ...

I use Stripe Checkout links to sell monthly subscriptions and I run my AI video service through the Runway ML API. What I need is a small, secure webhook that listens to Stripe events, recognises the subscription tier a customer just paid for, and immediately calls the Runway ML REST endpoint to top up that customer’s usage. The flow should handle multiple subscription tiers (Basic, Pro, etc.), mapping each tier to a different credit amount in Runway ML. On a successful payment— or —the webhook must: • validate the Stripe signature • read the product / price ID to identify the tier • post the correct credit to Runway ML via its REST API • log the action to prevent double-crediting and for later auditing • return a 200 response so Stripe ...

I need a production-ready crypto exchange site that lets users trade on a live spot market with Bitcoin, Ethereum, Ripple and USDT from day one, with the option to add more pairs later.

Please plan for regular penetration testing and clear audit logs. A clean React (or Vue) front-end talking to a Node.js, Go or comparable back-end is preferred, but I’m open to other proven stacks if you can demonstrate equal or better ...

I need a complete system that lets users find and reserve sports venues online.

An intuitive calendar view, automated email/SMS reminders, and a simple cancellation / refund module are essential. I also want a backend dashboard where venue owners can add photos, set pricing, block out dates, run basic reports, and track payouts. Role-based access for admins, venue managers, and end-users should be baked in from the start. Clean, modern UI/UX, responsive design, and solid performance are more important to me than any p...

I am building a web application and want one proven engineer to take full ownership of the tech. The current plan is React on the front end and Python on the back end; if you favour Django, FastAPI, or another modern framework that fits, make the case and run with it. You will design the database, craft the APIs, set up the cloud infrastructure, and push clean, tested code to production without constant check-ins.

I need a complete, production-ready website focused on community building. The core experience should let members create posts, share content in a scrolling feed, and interact in real-time through live chat rooms as well as smaller, interest-based groups or circles. A smooth onboarding flow, profile management, notifications, and a clean, mobile-first interface are essential. Beyond conversation, the platform must be flexible enough to add buying-and-selling features later, so structure the database and API with scalability in mind. Think modular components, reusable UI patterns, and clear separation between core community features and potential marketplace extensions. Tech stack is up to you, but I expect modern standards—responsive front-end (React, Vue, or similar), real-time ca...

Take My App To 100% My cross-platform app is already live on both the App Store and Play Store and generally runs well, but a handful of finishing touches are holding it back from perfect. I need someone who can jump into an existing codebase and knock out the last few issues so the product feels rock-solid to every user. I can help you with Claude subscription. Key areas that need attention • iOS voice feature – the functionality is coded but the permission handshake is failing on some devices, so the microphone dialog never appears. • Backend stability – the Node.js API on AWS (EC2 + MongoDB Atlas) goes down intermittently and response times spike under load. I want logs cleaned up, memory leaks traced, and sensible auto-scaling or monitoring put in place. •...

I’m ready to turn PageVault’s lightning-fast compression API into the backbone of a multi-channel eBook storefront. The core task is to wire the existing REST endpoints so they not only shrink large publication files on the fly but also let customers purchase and download them seamlessly. Here’s what the finished solution should do: • Accept an uploader’s original EPUB, MOBI or PDF, route it through the PageVault compression service, then store the optimized asset in my cloud bucket. • Push the final, compliant files to Amazon Kindle, Apple iBooks and Google Play Books from a single dashboard, keeping each platform’s metadata requirements in mind. • Present buyers with a secure payment gateway (Stripe preferred, though I’m open to a...

I’m building a browser-based workflow management application whose core purpose is accurate task-level time tracking. The platform should allow users to start, pause, and stop timers on individual tasks, then automatically log those entries against the correct project so I can see where every minute goes. Beyond the timer itself, I need two key add-ons: • Reporting tools — interactive dashboards plus exportable reports (PDF or CSV) that break down hours by person, project, and date range. • User role management — at minimum Admin, Manager, and Worker levels with granular permissions for creating tasks, viewing reports, and editing time entries. A simple efficiency calculator is also required: the system should compare logged hours against an estimated basel...
