I'm Abdul Rafeh — a passionate developer with over 5 years of experience building fast, scalable, and user-friendly web and mobile applications. I work with React Native, React.js, and Next.js to craft smooth, responsive frontends, and I love bringing ideas to life across iOS, Android, and the web. I also work extensively on the backend, using NestJS and Node.js to build clean, modular APIs that scale well and keep things running smoothly behind the scenes. Over the years, I’ve had the chance to dive into some exciting areas like blockchain and Web3, integrating tools like Ethers.js, Wagmi, and RainbowKit. More recently, I’ve been working with AI agents like OpenAI and Claude, using LLMs to build smarter, more interactive user experiences. Whether it's creating full-stack applications, integrating payment systems, or building chatbots and decentralized apps, I love solving real problems with code. Tech I work with: React Native • React.js • Next.js • Node.js • NestJS • Express • Firebase • PostgreSQL • MongoDB • Supabase • Zustand • Redux Toolkit • Tailwind CSS • GraphQL • Wagmi • Ethers.js • RainbowKit • Solana • AWS • PWA • OpenAI • Claude • Whisper • Deepgram • Stability AI • TensorFlow.js • RevenueCat • Mixpanel • HubSpot • Stripe • Expo • WalletConnect

Full-stack developer based in San Francisco (PST). I take founders from idea to a live, production app, fast, and with senior-level execution. In the past year I've shipped 5 products end-to-end: • ChekBack - a receipt-cashback app • PhotoOffice - an AI passport-photo service • ChessTourism - a chess-tournament platform • Pluto - a field-service management system for home-service companies • MotoSocial - a social network for motorcyclists Each one went from concept to deployment, including auth, payments, integrations, and infrastructure. Why clients work with me: • US-based, real-time overlap with your business hours • Native, clear English on calls and in writing • Senior delivery - I ship working software, not just plans • I stay with you until your app is published - I never leave you alone with your issues or concerns • Warranty after delivery - if something breaks on my work, I fix it, no extra charge Core stack: React, React Native, Next.js, TypeScript, Node.js, PostgreSQL. Also: Python (FastAPI/Django), Expo, Redis, AWS/Hetzner/Cloudflare, CI/CD, REST & GraphQL, CRM and third-party integrations. Best fit for: founders and startups who need an MVP or full product built right, the first time. Send me your idea and I'll reply with a rough scope and timeline. No charge.
