Mohansai Mallineni
Full Stack Developer — React / Next.js / TypeScript / MERN
Frontend-focused full stack engineer specializing in scalable React & Next.js applications — with hands-on production experience in TypeScript and the MERN stack. I craft performant, accessible, and modern UIs that deliver real business value.
About Me
I'm Mohansai Mallineni, a frontend-focused full stack developer with 4+ years of experience building enterprise-grade, performant web applications using React, Next.js, and TypeScript. I specialize in crafting scalable, maintainable UI systems with a strong eye for UX and accessibility.
At DIRECTV and CUNA Mutual, I've delivered production-ready features in Agile teams—architecting CMS-driven components, refactoring API logic for reusability, and implementing role-based UI controls. I'm confident across the MERN stack (MongoDB, Express, React, Node.js) with hands-on experience in Redux, Material UI, and backend routing logic.
Recognized with the “Working as One” and “Doing the Right Thing” awards for initiative, delivery ownership, and team collaboration. I take pride in clean code, clear thinking, and continuous learning — always shipping with purpose.
