Sachin kumarSachin Kumar - Principal Front-End Engineer
Principal Front-End Engineer with 15+ years building and owning complex UI platforms across banking, fintech, e-commerce, and SaaS. I operate at the intersection of engineering leadership and hands-on delivery — setting frontend direction, defining architecture, and raising the bar for quality and performance across teams.
Deep expertise in React, TypeScript, Micro-Frontends (Webpack Module Federation), and Design Systems. I've led multi-team frontend programmes in high-stakes, regulated environments — from greenfield platform builds to scaling legacy systems without breaking them.
I care about the things that compound: clear architecture decisions, well-documented systems, and engineering cultures where teams ship with confidence.
