Go, TypeScript, Python. Backend generalist leaning toward AI infra: Postgres, pgvector, Redis, gRPC, Kubernetes, RAG pipelines, agent orchestration.

Digging into agent orchestration internals: hand-rolled state machines vs LangGraph, RAGAS-driven eval loops, and token-efficient tool design for LLM harnesses like Claude Code.

repi, an autonomous log investigation agent (hybrid retrieval, state-machine loop, RAGAS-evaluated across 5 models), and smrit, token-efficient MCP tooling for LLM coding harnesses.

Chats on production RAG, agent orchestration, retrieval evaluation, or Go backend infra. Also open to backend / AI infra roles in Bangalore. Say hi if any of that overlaps.
