Hi, I’m Prasan Mishra, a frontend developer specializing in building fast, accessible user interfaces with React and Next.js. Recently I led the modernization of a large ATS platform at Internshala, migrating from legacy queries to a modern stack (React, TypeScript, Next.js) and achieving notable performance gains in LCP, TTI, and Lighthouse scores while preserving feature parity. I enjoy collaborating with product and design teams to ship features that enhance UX and stability. I’ve hands-on experience in optimizing caching and repository structure, improving data retrieval performance, and integrating payment gateways to support reliable services. I’m always learning new tools and love contributing to open-source projects.…Hi, I’m Prasan Mishra, a frontend developer specializing in building fast, accessible user interfaces with React and Next.js.
