I build production AI agents end to end: the agent loop, retrieval, evals, tracing and cost. I co-founded TeachPad (teachpad.in), an AI teaching-prep platform for Indian school teachers, and wrote most of its code. 6,900+ teachers have signed up. Its agent, Elif, is the signed-in home page: it answers from the teacher's own textbook, cites the chapter, and asks instead of guessing. I picked its models with a 4-model A/B test on grounding, and dropped vector search from document generation after measuring 6.5x more hallucinations than whole chapters. Every turn is traced in Langfuse, with spend metered per model. Now I'm a Senior Software Engineer at Tracxn, working on its customer-facing AI assistant. Before that I was the sole engineer at an Indian tax-compliance firm: a Node.js/TypeScript platform on Postgres, a 40+-tool Claude agent that asks a human before it writes, and hybrid search on pgvector. TypeScript, Python, Postgres, GCP and AWS. Claude Code and Codex daily. I work well async, in docs and PRs. TeachPad is live, and I'm looking for the next thing to build from zero: a remote role owning an agent or AI product. Bangalore, IST.
