About me

I'm a Senior Full Stack Developer with 5+ years of experience turning ambitious ideas into production software that real businesses rely on every day. I've shipped SaaS platforms, AI-powered products, healthcare systems, e-commerce stores and WebAR experiences — end to end, from architecture to deployment.

My sweet spot is the backend: Django, FastAPI, Node.js and NestJS, paired with polished React and Next.js frontends. Recently I've been deep in applied AI — LLM-powered assistants with RAG, vector databases and custom ML model serving — plus the OAuth2, Stripe and DevOps plumbing that separates production products from prototypes. I also build the APIs and infrastructure that power iOS and Android clients.

If you need someone who can own a feature from whiteboard to deploy — and communicate clearly the whole way — let's talk.
