- Full-stack engineer at Techorigins, Kolkata, India. Lead engineer on 14+ products in 2 years.
- I work across the stack: React / Next.js on the front, Django / FastAPI / Node on the back, Postgres + Redis underneath.
- I build AI tools that hold up in production: MCP servers, agents, RAG and LLM evals.
- 3x hackathon winner (Sibyl Labs, Syndicate by Maximor, Build with Elements by Unlayer).
- Open to full-time remote roles.
| ⚡ 5 min → under 1 s | Rebuilt a slow endpoint with query fixes, cursor pagination and three-tier Redis caching |
| 🧹 ~1M records deduped | Matched records across 4 data providers with Postgres pg_trgm |
| 🎯 ~70% → 90%+ accuracy | Built an A/B eval harness on labeled data for an LLM classifier |
| 🤖 52% fewer tool calls | Cairn vs Playwright MCP, measured over 90 benchmarked agent sessions |
- Graphify (YC S26): 47 commits shipped, including a Python call-graph feature (+8 pts call recall), a 1.5x faster Windows build and a ~300x faster MCP shortest-path query.
- OpenClaw: merged PR that stopped default vaults being dropped during memory-wiki configure.
- Reflex: merged PR that fixed the dashboard tutorial's dialog closing before validation ran.
