I'm a passionate Front End Developer based in Kolkata, India, with 2+ years of hands-on experience building modern web applications for startups and enterprise clients. I thrive on creating beautiful, functional interfaces that deliver real business value.
My journey in web development started from a deep curiosity about how the web works, and evolved into a full career building ERP systems, CRM platforms, mobile-first web apps, and open-source component frameworks. I believe every pixel matters and every millisecond counts — and I bring that mindset to every project I work on.
