About this gig

Backend throwing 500s, auth breaking, or a query that suddenly got slow? I'll find the root cause and fix it properly, with a test so it stays fixed.

I'm a backend engineer (ex-Swiggy) working with Python/FastAPI and Java/Spring Boot, PostgreSQL and Redis. At Swiggy I built production backend features and worked on Redis cache optimisation.

What I fix:

  • API errors, crashes and wrong responses
  • Authentication issues (JWT, sessions, OAuth)
  • Database bugs, bad migrations, slow queries
  • Redis caching problems
  • Payment webhook failures (Stripe, Razorpay)
  • Docker and deployment errors

How it works:

  1. Message me the error, logs and repo access before ordering, so I can confirm scope and price.
  2. I reproduce the bug and write a failing test.
  3. I fix the root cause, not the symptom.
  4. You get the fix, tests and a short note on what changed and why.

Not sure which package fits? Send me a message first.
