Full-Stack Web Developer for New Features I had a great experience working with this developer. They understood the new features I needed, communicated clearly throughout the project, and handled the work professionally. Everything was completed smoothly, and the final result worked exactly as expected. I’d definitely be happy to work with them again.

San Francisco, United States - 11:44 pm local time
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.
