If your Rails app needs to scale, ship faster, add AI features, or finally get refactored properly, that's the problem I solve. I'm a full-stack Ruby on Rails developer with 7+ years building SaaS platforms, APIs, and custom web applications, plus the AI features and cloud infrastructure around them. Clients bring me in when they need one engineer who can own the project end to end without constant oversight. 100% Job Success across all engagements.
