Building products at the intersection of Web3, fintech, and great UX

01 / About
Who I Am
I'm a Tech Lead & Senior Frontend Engineer with over 9 years of experience crafting high-performance web applications. Currently solo-architecting and building the entire product at PandaMoney — frontend, backend (Go), and cloud infrastructure (AWS) — from the ground up.
My journey has taken me through some of India's most impactful tech companies — from architecting blockchain-based platforms at Six Sigma Sports to scaling consumer products at Paytm serving millions of users. I specialize in building complex, real-time applications with a deep focus on performance, developer experience, and polished UX.
I'm particularly drawn to the intersection of Generative AI, Web3, and frontend engineering — where cutting-edge technology meets real user impact. I leverage AI-assisted development and LLM integrations to rapidly prototype and ship production-grade products. Whether it's building AI-powered features, integrating DeFi wallets, or designing component architectures that scale, I bring a product-minded approach to every line of code.
