I’m a Senior Frontend Engineer with 3+ years of experience building production-grade web applications for high-traffic media platforms, startups, and enterprise organizations. I specialize in scalable React, Next.js, and TypeScript architectures serving over 1M+ active monthly users.

My key platforms include Kiska Kitna Hisab (full-stack group expense and instant UPI payment settlement app), Shopperce AI (multi-tenant customizable eCommerce architecture), LiveLaw (India's premier legal news platform), and NextLeap IT Solutions (enterprise corporate services).

I care deeply about Core Web Vitals (LCP, INP, CLS), component modularity, and pixel-perfect design execution. Every project is engineered with strict type safety, responsive layout precision, and fast, frictionless rendering.
