Software Development Engineer | React, Next.js, TypeScript | High-Performance Web & PWA Apps

About

I’m a Frontend Engineer specializing in building fast, scalable, and intuitive web experiences using React.js, Next.js, and TypeScript, with a strong focus on performance-first architectures and real-world product impact. At Park+, I’ve worked on high-traffic consumer products like Vehicle Search, Toll Assist, and e-Challan, where I improved page load times, SEO, and Core Web Vitals by leveraging ISR, parallel API fetching, caching, and code-splitting. I’ve also built reusable component systems that improved UI consistency and accelerated development across teams. Previously at Phenom People, I contributed to the Service Hub platform by building user-friendly frontend components, integrating full-stack features, and collaborating closely with backend teams to deliver reliable and scalable solutions. I enjoy solving complex UI and performance challenges, take strong ownership of features, and continuously push myself to build clean, maintainable, and high-impact products.
