About me

I’m a Software Engineer with 8+ years of experience building and modernizing scalable Ruby on Rails applications. Much of my work centers on upgrading and refactoring legacy Ruby/Rails systems into faster, more maintainable architecturesβ€”whether migrating monoliths to API-driven services, improving database performance, or modernizing frontends with Vue.js.

I’ve led performance overhauls (including a 90%+ reporting speedup), optimized major query bottlenecks, introduced coding standards, and helped teams safely upgrade and stabilize old Ruby projects that were critical to business operations. I also build secure integrations, high-traffic APIs, and mobile backends used by thousands of users.g
