Remote-first mindset with availability for global product teams.

A frontend engineer who treats interface quality as part of the product strategy, not decoration.

Senior Frontend / Fullstack Web Developer with 4+ years of experience building high-performance product surfaces, scalable web applications, and complex frontend integrations.

My strongest work sits at the intersection of UI craft, technical architecture, and delivery discipline. That includes SaaS platforms, real-time features, embedded systems, and enterprise-facing interfaces that need to feel stable and polished under real constraints.

I care about the details recruiters and hiring managers often notice immediately: visual clarity, credible messaging, thoughtful hierarchy, and a sense that the engineer behind the work understands product quality end to end.
