Senior Frontend Engineer
Hi, I'm Siddharth — I design interfaces that feel human, useful, and fast.
Building modern frontend products with React, Next.js, TypeScript, Node.js, realtime systems, and developer-grade UI experiences.
I like turning complex product requirements into calm, usable interfaces.
I care about micro-interactions, empty states, component APIs, and performance budgets.
I am happiest when design, frontend architecture, and product thinking meet in one polished release.
