I build scalable React platforms, design systems, and high-performance frontend architecture for commerce and fintech.
IndiaWhat I'm looking for
I've led frontend delivery for Publicis Sapient, Signcatch, and a US multi-asset trading platform, building scalable web applications across fintech, telecom, and B2B commerce.
At Publicis Sapient, I delivered an AI-assisted conversational commerce proof of concept, built independently deployable microfrontend modules, and enabled multi-brand theming for telecom products. I also raised Lighthouse accessibility scores from about 70 to 95+ and reduced bundle size by about 30%.
At Signcatch, I directed frontend development for the ONDC B2B Buyer App, built reusable component systems, and helped modernize the React architecture. My work improved load performance by 30–35%, reduced production issues by 25%, and supported localization tied to 20% merchant growth.
Most recently, I led a four-person team shipping Phase 1 of a multi-asset trading platform, including equities, crypto, and fixed-income buy/sell flows. I build production-quality frontend foundations with Nx, React, TypeScript, accessible atomic design systems, automated testing, and spec-driven AI-assisted engineering practices.
