About this gig

Having a problem with your Ruby on Rails application? I can help you find and fix it.

Im a full-stack Ruby on Rails developer with 4+ years of professional experience working on production web applications and existing codebases.

I can help with:

  • Slow queries and performance issues
  • Third-party API integrations
  • Authentication and authorization
  • Sidekiq/background jobs
  • RSpec and failing tests
  • Docker and development environment issues
  • Ruby/Rails maintenance and upgrades
  • Small refactoring and code cleanup

How it works:

  1. You provide the problem and relevant information.
  2. I investigate the root cause.
  3. I implement and test the fix.
  4. I explain what was changed.

I work with existing Ruby on Rails applications and can help with both straightforward bugs and more complex issues.
