Founding Engineer at Takkada, building PaySaathi, a production accounting & ERP platform across Flutter, Supabase, PostgreSQL, Edge Functions, and Next.js.

Previously SDE-1 Backend at Zomato, working on high-scale CX services in Go, gRPC, MySQL, and MongoDB, including a ~5× p90 latency improvement.

What I do

  • Backend engineering: Go, gRPC, REST APIs, concurrency, retries, idempotency, background workers
  • Distributed systems: leases, fencing, failure recovery, workflow execution
  • Infrastructure: Docker, PostgreSQL, Linux, CI/CD
  • Full-stack / product engineering: TypeScript, Node.js, Next.js
  • Open source: 100+ merged pull requests across backend, infrastructure, databases, developer tooling, and systems projects

Core stack: Go, TypeScript, Node.js, Next.js, PostgreSQL, gRPC, Docker, C++, Python

Strong projects

  • DurableGo — Crash-safe durable workflow engine in Go with PostgreSQL-backed execution, leases, fencing, retries, idempotency, and recovery.
  • QuantXecute — Real-time trade-cost estimator for crypto futures. Streams OKX Level 2 orderbook data over WebSocket and models execution costs in C++.
  • ParseFlow AI — Document intake pipeline with OCR, classification, schema-constrained LLM extraction, field-level provenance, validation, duplicate detection, human review, and audit history.

Open source

100+ merged open-source pull requests across backend, infrastructure, databases, developer tooling, and systems projects.

Recent contributions include correctness and systems fixes in projects such as SeaweedFS, Plane, Qdrant, NetBird, and Prefect.
