What I'm looking for

I am looking for a fully remote or Europe-based frontend role where I can lead frontend architecture, mentor engineers, and improve performance and developer velocity while collaborating closely with product and design.

I am a senior frontend developer with 8+ years building scalable, performant, and user-centric web applications using React, TypeScript, Next.js, and modern frontend architectures. I lead frontend architecture, drive engineering standards, and mentor engineers while delivering measurable improvements in performance and reliability.

My achievements include migrating legacy apps to TypeScript, improving load speed by 45% through Core Web Vitals optimization, reducing production bugs by 40% via engineering standards, and building a shared design system with Storybook to ensure UI consistency across product lines. I seek fully remote or Europe-based roles and bring strong collaboration with product, design, and backend teams.
