Who I Am

I'm a Frontend Developer based in Kolkata, India, with 2+ years of experience building production-grade web applications that are fast, accessible, and genuinely enjoyable to use.

By day I work at Tech Mahindra on an automotive e-commerce platform for a global car manufacturer — shipping everything from AI-powered conversational search to pixel-perfect UI component libraries.

I care deeply about performance (Core Web Vitals, 90+ Lighthouse), clean component architecture, and the small details that make a product feel polished.

Currently exploring full-stack development — building Node.js APIs and learning backend architecture to complement my frontend expertise.
