Project details
Stop letting small bugs disrupt your user experience.
I provide rapid, reliable Ruby on Rails debugging to get your application back on track. With 5 years of backend experience, I specialize in identifying the root cause of "mysterious" errors, whether they are database bottlenecks, failing background jobs in Sidekiq, or broken API endpoints.
What sets this project apart:
Deep Root Cause Analysis: I don't just "patch" the symptoms; I fix the underlying logic.
Security-First: Every fix is checked against common Rails vulnerabilities (XSS, SQL Injection).
Zero Regressions: I verify fixes with RSpec to ensure we don't break existing features.
