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.
