Background

About Aritro Roy

I’m a backend engineer who loves solving problems at scale. At my current company, I built a referral system that supports 100-level chains and handles over events per minute. It’s rewarding to know that my work directly impacts millions of users. Before this, I was at Intract, where I built high-throughput services used by over 1 million people every day. One of my favorite projects was an async verification system that had to stay fast and reliable—even under peak loads. I started my journey at BYJU’S, where I worked on systems supporting tutors and over a million classrooms. This taught me how to build with both scale and user needs in mind. I also enjoy mentoring. At Scaler, I’ve taught advanced data structures and algorithms to hundreds of students. Helping others grow keeps me grounded and inspired. Outside of work, I explore new technologies and contribute to projects that promote learning in underserved communities. I believe tech should be accessible to everyone.
