Zubin Choudhary

Contract Product Engineer

I ship hard-to-ship product features.

I work with startups and product teams on important technical work that spans too many systems for a simple handoff: complex integrations, backend-heavy features, desktop apps, and specialized systems work including Web3 when relevant.

Tauri desktop product with 130 GitHub stars • ERC-4337 SDK + demo app • GSoC alumnus • Commercial internal-tool delivery

What teams bring me in for

  • A feature that keeps slipping because it touches too many systems.
  • A tricky integration that needs careful implementation, not glue code.
  • A backend-heavy product slice that needs end-to-end ownership.
  • A short sprint to de-risk an important technical decision.

Engagements

Spike Sprint

5 days to de-risk one technical problem with a working implementation slice, technical notes, and a rollout path.

Build Sprint

2 to 4 weeks to ship a feature or integration end-to-end.

Technical Rescue

A short engagement to stabilize a fragile code path or unblock a delayed feature.
