01 / About

Hands-on engineering with technical ownership.

I build and improve web experiences where engineering quality, developer experience and business outcomes meet. My work spans architecture, UI engineering, performance, SEO, accessibility, CI/CD, production readiness and release management.

As a Technical Lead / Team Lead, I drive solution planning, technical design, code reviews, root-cause analysis, cross-functional execution and mentoring — while staying close to the code.
