What I'm looking for

Frontend engineer with 8+ years of experience building scalable, high-performance web applications using ReactJS, Next.js, TypeScript, Redux, and modern frontend technologies. Looking for product-driven teams where I can contribute to frontend architecture, performance optimization, and impactful user experiences in SaaS, AI, FinTech, or remote-first environments.

I’m a Senior Frontend Developer with 8+ years building scalable web and mobile applications using React JS, Next.js, TypeScript, Redux Toolkit, and Ionic Framework. I’ve shipped production applications across Android and iOS, including PrivaSea (an NFT wallet) and Qila (a full-featured web platform).

I deliver enterprise-grade, user-focused experiences—most notably a Role-Based Access Control portal for Mahindra & Mahindra, serving 5,000+ internal users. I integrate REST APIs confidently, write Jest/RTL unit tests, and optimize performance through code splitting, lazy loading, and Core Web Vitals tuning.

I thrive in Agile/Scrum teams, collaborating closely with designers, backend engineers, and QA to ship reliably and iterate fast. From Webpack/Vite and build pipeline improvements to accessibility and responsive, mobile-first UI, I focus on measurable outcomes and production quality.
