About

I'm Harsh, a senior frontend engineer with 3+ years of turning milliseconds into money. From building battle-tested design systems at Redbus to shipping performant Svelte micro-frontends for Razorpay’s global checkout flows, I specialize in crafting experiences that scale, convert, and delight. Whether it’s cutting user's wait time from 400ms to 160ms across multiple countries and platform, launching an open-source library with 5K+ weekly downloads, or mentoring teams to ship faster and cleaner - I bring ownership, obsession with performance, and an eye for clean abstractions. If it runs in the browser, I make it faster. If it breaks, I fix it before you notice. And if it’s complex, I modularize and ship it with tests. Building web that works like magic. Currently learning AI | ML | RAG | Agentic Workflow. !not from Tier-1 / IIT / IIM / NIT.
