About

I’m a Frontend Engineer who enjoys building web experiences that are fast, reliable, and actually pleasant to use. Over the last 3.5+ years, I’ve worked with React, Angular, and Node.js, mostly on large-scale products where performance and user experience really matter. Currently, I work at Adani Digital Labs / Trainman, where I’ve helped improve and scale consumer-facing platforms used by millions of users. One of the most rewarding parts of my work was leading the migration of a legacy Angular application to React and Express, which cut load times by nearly 70% and noticeably improved SEO and user retention. Seeing real users benefit from these changes is what keeps me motivated. I care a lot about clean code, performance, and security. I like digging into Lighthouse reports, fixing bottlenecks, and leaving the codebase better than I found it. I also enjoy code reviews and collaborating with teammates to keep things simple, readable, and maintainable. Outside of day-to-day features, I’ve worked on: Performance optimizations (lazy loading, code splitting, SSR) Angular upgrades and white-label integrations Secure authentication and frontend security practices Modular and scalable frontend architecture Tech I’m comfortable with: React, Next.JS, Angular, JavaScript, TypeScript, Node.js, Express, Redux, HTML, CSS, along with tools like Docker, CI/CD, Lighthouse, Grafana, and Git. I’m someone who enjoys learning, asking why, and building things that solve real problems. Always happy to connect with people who care about good products, good code, and good teamwork.
