About me
I am a Senior Full Stack Developer with 5+ years of experience turning ambitious ideas into production software that real businesses rely on every day. I have shipped SaaS platforms, AI 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 have been deep in applied AI, building LLM assistants with RAG, vector databases and custom ML model serving, along with the OAuth2, Stripe and DevOps work 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.
