01 — About

Building products at scale.

Bengaluru, India · UTC+5:30

I'm a Software Engineer II at Fanatics with 4+ years of experience building scalable web applications, AI-powered products, and customer-facing experiences used by millions of users.

At Fanatics, I work across the full stack using React, Go, GraphQL, and cloud technologies to deliver high-impact features. My recent work focuses on AI-driven product experiences, personalization systems, and large-scale e-commerce platforms.

I enjoy solving complex engineering challenges involving system design, distributed systems, and performance optimization. I'm passionate about building reliable software that scales and delivers measurable business impact.

Outside of work, I actively practice data structures and algorithms on LeetCode, explore modern system architecture patterns, and continuously learn new technologies to sharpen my engineering skills.

"Build scalable systems. Solve meaningful problems. Keep learning."
