What I'm looking for

I seek senior frontend roles building scalable UI platforms, design systems, and performance-first experiences in product-focused teams that value measurable impact and engineering mentorship.

I am a Staff Frontend Engineer with 13+ years building enterprise‑scale UI architectures, focused on React and TypeScript. I design and deliver scalable component libraries, microfrontends, and design systems that accelerate feature delivery and maintainability.

I specialize in web performance and Core Web Vitals optimization, having driven measurable improvements such as a 35% load time reduction and raising Lighthouse scores from 42 to 91 in production. I also reduced bundle sizes by ~52% through module federation, tree‑shaking, and asset compression.

My experience spans experimentation and personalization platforms, A/B testing–ready UI architectures, and real‑time systems supporting large concurrent device counts. I lead cross‑functional teams, set code quality standards, and mentor engineers to scale engineering culture.

I deliver pragmatic, product‑aligned engineering: building CI/CD pipelines, robust testing (Jest, RTL, Cypress), and resilient integrations (REST, GraphQL, WebSockets) to ensure performant, accessible, and secure user experiences.
