About
A bit more about me
Builder, mentor, and frontend specialist who cares as much about people and product as about pixels and performance.
With 9+ years in software development, I specialize in leading frontend engineering with a focus on clean architecture, maintainability, and performance. I've guided cross-functional teams, mentored developers, and built systems that scale with both product needs and business growth.
My work blends technical precision with a strong UX/UI sensibility — whether architecting complex interfaces, driving performance optimizations, or partnering closely with product and design.
