About Me

Curious by nature. Software engineer by choice.

I still remember several instances of me pry opening my toys as a kid, not because it was broken, but because I wanted to see how it worked. I've always been fascinated by understanding why something works, how it works, and whether I could build it myself. That curiosity eventually led me to software engineering, where every project is another opportunity to learn something new.

One of the most rewarding experiences so far was leading a team of three engineers at the IICPC Summer Hackathon 2026. We built TradeBench, a distributed platform for benchmarking trading exchange engines under concurrent workloads using microservices, gRPC, and Redis Streams. Among more than 2,000 teams across India, we finished 10th nationally, while also getting the chance to interact with engineers from Optiver and HRT.

I enjoy building software that teaches me something. Whether it was writing a concurrent DNS resolver in Go that processes over 23,000 queries per second, optimizing authentication and database performance during my internship, or experimenting with distributed systems, I'm most motivated by solving problems and understanding the systems underneath.

I graduated with a Bachelor's degree in Electronics & Communication Engineering from Heritage Institute of Technology in July 2026. I'm currently seeking Software Engineering, Backend Engineering, and Systems Engineering opportunities where I can continue learning, build meaningful software, and collaborate with talented teams.

TradeBench

Distributed Trading Engine Benchmarking Platform

A distributed platform that stress-tests user-submitted trading exchange engines under concurrent load. Architected a 4-service system using gRPC for inter-service contracts and Redis Streams for async job queuing — with sandbox security for untrusted code: non-root, read-only FS, capability dropping, network isolation.
