In my last ~9 years of experience, I have worked at D. E. Shaw, Practo, Amazon, and Unacademy; and have built systems, services, and platforms that scaled to billions.

Post my masters in CSE from IIIT Hyderabad I joined D. E. Shaw for a short stint of 2 months, before moving to Practo and working there as a Platform Engineer, building and owning close to 8 different microservices. Post Practo I worked at Amazon on their primary mission-critical E-Commerce Database and built Data Pipelines that cold tiered the stale data.

After quitting Amazon in 2018, I joined Unacademy as their first Technical Architect and there I designed, built, managed, and scaled services like Search, Notification, Logging, Deployment Engine, and many more. I have now transitioned into the role of a Sr. Engineering Manager, leading the Site Reliability vertical.

In January 2020, I started my newsletter where I write and share an essay about programming languages internals, deep dives on some super-clever algorithms, and few tips on building scalable distributed systems. The newsletter currently has close to 2000+ subscribers.

Recently, I have started building Revine - a programming langauge for kids helping them develop logic through animations and spark their creativity through artwork.
