I will debug your API, fix webhooks, or resolve backend errors in go or python
Lawson O
Over deze dienst
Is your API throwing random errors? Webhooks not triggering? Background jobs failing silently?
I fix these tricky backend issues fast usually within 24-48 hours.
Common problems I solve:
- Runtime or compilation errors that don't appear locally
- Webhooks that arrive but fail to process
- Background tasks (Celery, Redis queues, etc.) that die silently
- Poor error handling that masks the real issue
- Idempotency bugs causing duplicate charges or data corruption
You could try fixing it with AI, but I've seen it send developers down rabbit holes chasing ghosts, breaking production, and losing days. I won't do that to you.
I'm a backend engineer with 3+ years building production fintech systems in Go and Python. I've debugged live payment flows, fixed accounting discrepancies, and stabilized critical backend services handling real money.
What you get:
- Clear root cause analysis (written in plain English)
- Clean, fixed code
- One-page prevention guide so it doesn't happen again
No fix? No payment. I'll let you know within 24 hours if it's outside my scope.
Pick the package that matches your needs I'll reply within 2 hours.

Veelgestelde vragen
How do I share my code with you without exposing secrets?
You share your code repository (GitHub, GitLab, or zip file) with sensitive values removed. Use environment variables or a .env.example file. Never share live API keys, database passwords, or secret tokens. If your bug requires live data, I'll show you how to safely share sanitized logs or a staging
What if you can't fix my bug after I order?
I will tell you within 24 hours if I cannot solve your issue. If that happens, you pay nothing. I will cancel the order or guide you to a more specific expert. No wasted time. No hard feelings.
Do you work with my existing codebase or start from scratch?
I work directly with YOUR code. I don't rewrite from scratch unless we agree on that separately. I find the specific error, fix it, and leave the rest untouched. Minimal changes. Maximum impact.
What backend technologies do you actually fix?
I work with: Go (Fiber, Gin, standard library), Python (FastAPI, Flask, Django), REST APIs, Webhooks (incoming/outgoing), Celery + Redis, MongoDB, PostgreSQL, MySQL, and basic Docker setups. If your stack is very different, message me first before order
How fast will you start working on my order?
Once you order and send the requirements, I will respond within 2 hours (usually faster). I will confirm I understand the issue before starting. Most fixes are delivered within 1–2 days depending on complexity.
