I’m a Frontend Developer and Software Engineer with 5+ years of experience building high-performance, scalable web applications using React.js and Next.js. I focus on UI optimization, component-driven architecture, and real-time user experiences that feel fast and reliable.

At Grep Ruby Webtech Private Limited (Gammastack), I owned end-to-end frontend delivery—from requirement gathering and design discussions to development and deployment coordination. I enabled real-time live score updates for 10K+ concurrent users with low-latency performance (<200ms), delivered secure crypto & fiat payment integration for 1000+ daily users, and improved Core Web Vitals by reducing render time from 17s to 0.5s.

I also built secure, scalable application features, including role-based access control (RBAC) with secure CRUD permissions across modules, and implemented Redux/Redux-Saga state management to reduce API call redundancy by 20–30%. On top of that, I shipped PWA capabilities that drove 25–30% growth in active users and maintained production readiness with 99.9% uptime under load.

Earlier at Infosys Ltd., I built responsive, cross-browser UIs with React.js, Tailwind CSS, Material UI, and Shadcn, creating reusable component libraries to improve efficiency. I strengthened performance using Next.js SSR (30% load-time reduction), developed backend logic for a payment validation platform (99% accuracy across 1M+ monthly transactions), and mentored a team of 5 developers using Agile and TDD (Jest), cutting data processing time by 30%.
