Sumit Singh — Frontend Engineer

I build frontend systems that move metrics — not just interfaces. With 5+ years of engineering experience across logistics (DP World), healthcare e-commerce (Tata 1mg), fintech (Snapmint), and edtech (ByteLearn), I've owned the full frontend lifecycle: architecture decisions, performance optimization, design system adoption, and cross-functional delivery. At Tata 1mg, a targeted UX overhaul I led drove an 18% uplift in order conversion — working closely with product and data teams to validate hypotheses and ship iteratively. At Snapmint, I rebuilt legacy workflows from scratch, increasing engineering team productivity by 70% through reusable component systems and streamlined CI/CD processes. At ByteLearn, aggressive code-splitting and asset optimization cut load times by 30–35%, directly improving SEO rankings and organic traffic. What I focus on: → Frontend Architecture — Scalable component systems, micro frontend patterns, design system governance → Performance Engineering — Bundle optimization, code splitting, memoization, Core Web Vitals → Developer Experience — Reusable UI libraries, CI/CD pipelines, testable component boundaries → Observability — PostHog, Hotjar, Amplitude, Segment, Google Analytics integrations → Accessibility — WCAG compliance, semantic HTML, screen-reader-first development Tech I work with daily: React.js · Next.js · TypeScript · Redux · Tailwind CSS · React Native · Node.js · Webpack · Jest · Figma I'm currently exploring system design at scale, DSA fundamentals for FAANG-level interviews, and building side projects in the React Native / mobile space. If you're hiring senior frontend engineers who think in systems, ship with ownership, and care deeply about user impact — let's connect. 📧 sumitsingh841208@gmail.com | 🌐 layout-logic.vercel.app
