About me
Engineering products end to end, from the first schema to the final deploy
I work across the whole stack: React and Next.js on the front end, Node.js, Python and FastAPI behind it, and LLMs, RAG and AI agents wherever they genuinely improve the product.
Most of my work is for founders and teams who need a system that stays secure and maintainable once real users arrive, with tenant isolation, role-based access, tested deployments and a clean hand-over.
- Multi-tenant SaaS with RBAC
- LLMs, RAG pipelines & AI agents
- Payments, telephony & third-party APIs
- Production deployment & clear hand-over
