What I'm looking for

I want remote work (visa sponsorship required if needed) where I can own the full frontend delivery cycle, build scalable Angular/React systems with micro-frontends, push performance, and collaborate with cross-functional teams while mentoring others.

I’m a Frontend Engineer with 5+ years of experience building scalable web applications for international teams and millions of users. I specialize in Angular and React, micro-frontend architecture, and web performance optimization, and I’m comfortable owning delivery end-to-end—from requirements to deployment.

In recent roles, I offloaded heavy computations to Web Workers, reducing main thread blocking by up to 99.82%, and I improved runtime performance by averaging ~65%. I architected a white-label Angular platform with dynamic configuration, migrated Angular to full standalone architecture to reduce build time by ~14%, and maintained cross-platform apps using Angular and Ionic from a single codebase.

I also lead with clarity and engineering discipline: I authored PRDs/TRDs, wrote technical documentation, and supported cross-functional squads through strong communication and mentoring. Across teams, I’ve introduced Module Federation micro-frontends, implemented Cypress E2E testing, built shared component libraries, improved observability for data-driven decisions, and applied WCAG accessibility standards to earn institutional recognition.
