What I'm looking for

I’m looking for a role where I can build scalable React/Next.js experiences, optimize Core Web Vitals, and deliver measurable performance wins—working closely with backend teams to ship clean, responsive SaaS UI that scales.

I’m a Front-End Developer with 7+ years of experience building scalable web applications using React.js, Next.js, and TypeScript. I focus on high-performance user interfaces, optimizing Core Web Vitals, and creating responsive UI systems for SaaS and product-based platforms.

I’ve delivered measurable impact across products, including reducing UI development time by 40% with a reusable component library, improving First Contentful Paint by 60% through Next.js SSR/ISR, and cutting production runtime errors by 25% using TypeScript and Zod. From real-time data synchronization with TanStack Query and Context API to performance gains like 200ms response times for critical features, I build frontend architecture that scales and keeps users engaged.
