Engineering Scalable Frontend Systems

Hi, I'm Saurav Gupta — a Frontend-Focused Software Engineer

I build performant, scalable, and user-centric applications across fintech, marketplaces, and B2B SaaS platforms. With deep expertise in modern web and mobile technologies like React.js, React Native, Next.js, TypeScript, GraphQL, Node.js, and Expo, I've led teams and shipped products that blend great UX with solid architecture.
