About

I am a Frontend Engineer who builds fast, scalable web applications. I focus on bridging the gap between complex backend systems and clean, intuitive user design. Currently, I work at Infosys, specializing in Generative AI UI and scalable architecture. In my current role, I led the frontend strategy for a GenAI-powered platform. I worked closely with cross-functional teams to build an interface that handles complex AI outputs while remaining easy for customers to use. This approach helped our product gain a strong foothold in a crowded market. Before this, I was a Digital Specialist Engineer focused on a high-scale ePharmacy platform. I led a full UI overhaul and updated the frontend architecture. These changes made the app faster and easier to navigate, which increased user retention by 90%. Earlier, at IDC Technologies, I focused on making web designs consistent across different apps. I used modern optimization tools to speed up page loads. This ensured a smooth experience for users, even on slower internet connections. I enjoy solving architectural puzzles using React.js, Next.js, and TypeScript. Outside of my daily tasks, I stay active in tech communities. I am always testing new frameworks to find better ways to build the web. I believe the best code is not just functional but also easy for other developers to maintain.
