I will fix bugs and errors in your ruby on rails application


About this gig
I'm a backend software engineer with 3.5+ years of hands-on Ruby on Rails experience, currently working on a production recruitment platform and previously at a software agency where I fixed production bugs daily for live client applications.
I can help you with:
- 500 errors, failed deployments, and broken migrations
- ActiveRecord / database query issues (including N+1 problems - I once cut a slow endpoint from 10s down to 1s)
- Broken third-party integrations (Stripe, payment gateways, APIs)
- Rails version or gem upgrade errors
- Background job (Sidekiq) failures
- Authentication / authorization bugs
- General "it used to work and now it doesn't" mysteries
How it works:
- Send me the error message, stack trace or a description of the unexpected behavior
- I'll review your codebase (read-only access or a shared repo is fine) and identify the root cause
- I fix it, explain what went wrong in plain English and hand it back no black-box fixes
I care about clean, maintainable solutions, not band-aid patches.
Message me before ordering if you're not sure which package fits. Happy to take a quick look first.

FAQ
Do you need repo access?
Yes, a GitHub/GitLab invite or a shared branch works. I don't need production server access unless the issue is environment-specific.
What if the bug takes longer than expected?
I'll tell you upfront if it looks bigger than the package scope before starting, so there are no surprises.
Can you work with an existing team's codebase?
Yes, I'm used to jumping into unfamiliar production codebases.
