Project details

Is your FastAPI, Spring Boot, or Node.js backend throwing
errors you can't figure out? I'll find the root cause and
fix it — not just patch it.

I have open source contributions merged by Tim Abbott
(Zulip founder/CEO) and Lee Calcote (Layer5/Meshery
founder) — 8 PRs across 4 CNCF orgs. I've built
production systems with Kafka, Redis, JWT auth, and
PostgreSQL RLS. 150+ tests shipped.

What I fix: REST API errors, authentication issues,
database query errors, Redis caching problems, Docker
and deployment issues, performance bottlenecks, CORS
and middleware errors.

You get working code, explanation of what was wrong,
and a revision if needed. Message me before ordering.
