What I'm looking for

I'm looking to build scalable production web applications where I can own features end-to-end, solve complex performance and reliability challenges, and apply AI-assisted development in a collaborative Agile engineering environment.

At Sabre Corporation, I build and maintain Ruby on Rails services and RESTful APIs for a global travel technology SaaS platform serving 500,000+ users. I own full-stack features with Rails and Angular, improve PostgreSQL performance, and resolve production issues from design through deployment.

Previously at Tecaudex, I delivered backend services for search analytics, learning management, and hotel booking platforms. I've shipped 20+ production-ready features across Rails, React.js, and Angular while using RSpec, TDD, Claude, Copilot, and ChatGPT to strengthen testing, debugging, refactoring, and delivery.
