About

In 4 years as a Frontend Engineer at Infosys, I've built enterprise-scale React applications used across multiple business units β€” improving dashboard rendering by 25%, building component libraries reused across 8+ modules, and integrating 10+ REST APIs end-to-end. I once got a message from QA saying "this is the most bug-free feature we've shipped." That's the bar I hold myself to. Here's what I've actually shipped: ⚑ Reduced page load time by ~30% through render optimization, lazy loading, and smart state management with Redux 🧩 Built reusable React component libraries that cut new feature development effort significantly across the team πŸ”Œ Integrated 10+ REST APIs with full coverage β€” async fetching, loading states, error handling, edge cases ☁️ Deployed on Azure Static Web Apps with CI/CD pipelines; daily Git branching, PR reviews, and Agile sprints πŸ“¦ Built Power Track (energy analytics dashboard) and Shop Ease (full MERN e-commerce app) as personal projects My stack: React.js Β· JavaScript (ES6+) Β· Angular Β· Redux Β· Context API Β· REST APIs Β· Node.js Β· Express Β· HTML5 Β· CSS3 Β· Git Β· Azure What I care about: βœ” Performance β€” because slow UIs are broken UIs βœ” Reusability β€” write once, use everywhere βœ” Documentation β€” future-me should thank present-me βœ” Communication β€” I keep QA, design, and product in sync I hold Infosys certifications in React and Frontend Development. CS graduate from Andhra University. Currently looking for Frontend Engineer roles at product-driven companies where I can own the UI layer, ship fast, and build things people use every day. Hiring for something like that? Or just want to talk React? Send me a message β€” I reply to everyone.
