At Sigma Solve, I build full-stack MERN applications and have improved page load and API response speed by 30%. I also develop reusable React component libraries and secure RESTful APIs and GraphQL endpoints.

At Shanti Infosoft LLP, I built Socket.io chat and notification features for the NAPS platform, supporting 3,000+ concurrent users. I also reduced React bundle size by 25% and cut average API response time by 35% through query optimization.

At Valere Labs, I led a frontend team of three React.js developers for the ClubRare NFT marketplace. I migrated components to React Hooks and integrated the Caver.js blockchain SDK on the Airdrop platform after a successful POC.
