02 — About

Good software
feels inevitable.

I’m a full-stack developer who builds SaaS products end to end — React and Next.js on the front, Node.js, Express and Nest.js behind, MongoDB or Postgres underneath, and AWS keeping it all running. Increasingly there’s an AI layer on top too: RAG pipelines and MCP servers that connect LLMs to real product data. I currently lead a small team at Metafic shipping PropTech and EdTech platforms.

I care about the parts users never see: multi-tenant architecture, message queues that don’t drop work, caching that makes pages 60% faster, and dashboards that flag trouble before anyone else does.
