What I'm looking for

I am looking for a role that challenges me technically and allows for growth in a collaborative environment.

I am a seasoned Ruby on Rails engineer with over 10 years of experience in building high-performance web applications and scalable APIs. My career has been marked by a proven track record of leading telecom SaaS platforms and developer infrastructure tools at top U.S. companies such as DMI, GitHub, and Basecamp. I excel in designing robust backends with Rails, optimizing performance with Sidekiq, Redis, and caching, and enhancing user experience with modern JavaScript frameworks.

At DMI, I orchestrated the overhaul of telecom billing systems, elevating client processes for major companies like Verizon and AT&T. My innovations in real-time data visualization and cost analytics have significantly reduced telecom waste and improved operational efficiency. I have a knack for shipping clean, maintainable code in fast-paced environments and driving technical improvements that deliver measurable business value.

My experience at GitHub involved developing and maintaining the GitHub Pages infrastructure, enabling millions of users to host static websites seamlessly. I have also engineered scalable billing platforms and enhanced security for millions of accounts. I am passionate about collaborating with cross-functional teams to ensure robust and secure applications, prioritizing continuous integration and delivery.
