(01) About

I'm Harshaan, a backend engineer and team lead. I build RAG services and APIs, and I lead by making production boring: fewer surprises, faster deploys, and failures that get written down before they get fixed.

Day to day: Python on PostgreSQL, Milvus, Redis and AWS. On my own time: Rust and Go. BSc Computer Science, University of Alberta · CompTIA Security+.

Open to senior backend and platform roles.
