Crafting high-performance digital experiences with React.js, Next.js, JavaScript and TypeScript. Building scalable web apps and dashboards with Node.js and REST APIs. 2.5 Years shipping production work.
I'm Pravin Singh, a frontend developer with 2.5+ years of experience building production-grade web products for startups and growing brands. Currently shipping core interfaces at Balance Nutrition, where I own features end-to-end — from Figma handoff to performance-tuned release.
My day-to-day stack is React, Next.js, TypeScript and Tailwind, backed by Node.js and REST APIs on the server side. I specialize in turning complex requirements into fast, accessible, SEO-friendly interfaces — and I obsess over Core Web Vitals, semantic markup, and the small interaction details that separate a good UI from a great one.
On the side I freelance as a full-stack developer — shipping landing pages, e-commerce platforms, and SaaS dashboards end-to-end, from frontend to APIs, database, and deployment. Always open to challenging work where craft and performance matter.
