What I'm looking for

I seek a senior frontend role where I can improve UI performance, lead frontend architecture, work cross-functionally, and mentor teams in a collaborative, delivery-focused environment.

I am a Senior Frontend Engineer with 10+ years of experience building performant, user-centric web applications using React.js, Next.js, TypeScript, and modern frontend toolchains. I have driven measurable improvements—reducing load times by 20%, cutting deployment times by 25%, and delivering a low-code platform that reduced development time by 30% over two years.

My experience spans enterprise and startup environments where I led small teams, designed UI/UX in Figma, integrated REST APIs, and implemented reusable component libraries and data visualizations. I focus on clean architecture, reliable CI/CD integration, and cross-functional collaboration to deliver solutions on time and at scale.
