About this gig

Full Stack / AI Engineer with 10+ years of experience building real, production-ready digital products not just prototypes.

I develop complete web applications using React, Next.js, and Node.js/NestJS, with PostgreSQL or Supabase for data, and AWS for deployment. I also specialize in integrating AI into real products: Claude/OpenAI APIs, RAG pipelines, and multi-agent architectures going beyond simple chatbot wrappers.

What I bring:

10+ years across frontend, backend, and full product delivery

Real client work (industrial, healthcare, and creative sectors)

Clean, documented, scalable code

Background in design/UX, so your app doesn't just work it feels right

Experience shipping SaaS products end-to-end, from idea to deployment

Whether you need a simple MVP, a full stack SaaS platform, or an app with real AI functionality built in, I'll build it properly with clear communication and no shortcuts.

Send me a message with your project details and I'll get back with a clear plan, timeline, and pricing.

Experience Engineer with 10+ years translating complex systems into clear, usable and sophisticated digital products. My background combines Fine Arts, frontend engineering, product thinking and AI-native interfaces — a profile built around understanding how things should feel to use, not just how they work. I design and build frontend systems where interaction, motion and UX clarity are as deliberate as the architecture behind them. Comfortable owning the full product surface: from design systems and component architecture to AI-powered interfaces and creative technology.
