I am a computer science researcher whose interests lie primarily in the Systems domain. I have been a part of projects in Cloud Computing, Distributed Systems and Computer Architecture. My current research is focused on the following areas:
- Utilizing recent advances such as RDMA and Programmable Switches (P4) to accelerate large-scale system performance
- Analyzing the impact of Networking Failures on large-scale software systems
- Analysis of modern-day Serverless Computing infrastructure to identify performance bottlenecks and optimization opportunities
I am enrolled in the PhD program in Computer Science at the University of Waterloo as a part of the Waterloo Advanced Systems Lab (WASL). My supervisor is Dr. Samer Al-Kiswany. Prior to this, I was enrolled in the research-based master's program at Waterloo from 2019-2021 and I have been a Design Engineer at Advanced Micro Devices (AMD) from 2017-2019.
I received my master's degree in Computer Science from the University of Waterloo in 2021, working under the supervision of Dr. Samer Al-Kiswany. I received my undergraduate degree in Computer Science from PES University in Bangalore, India and have been supervised by Dr. K.V Subramaniam and Dr. Phalachandra. I was a research assistant at CCBD during my time there.
I have experience developing systems in numerous languages such as C, C++, Java, JavaScript and Python along with limited experience in Solidity.

Side Projects
In my spare time, I like to develop applications using a variety of languages and tools to keep my skills sharp. Some of these projects and their source code are showcased in this section.
MuZero on Super Mario Bros
I have attempted to evaluate MuZero, an algorithm for deep learning published by Google Deepmind in 2019, against Deep-Q-Networks with Double-Q-Learning, the state of the art model free algorithm. I have compared their performance using the game Super Mario Bros. The system architectural diagram has been shown below:
Clips of an agent trained using MuZero playing the game can be found below:

The Crypto Lottery
This project consists of an Ethereum-based back end and a front end powered by React.js. The objective of this project was to build a lottery application where users register using Ether and stand a chance to win the Jackpot.
The Jackpot is the prize pool consisting of contributions from all participants with the winner being chosen at regular time intervals. A participants chances also increase with the Ether they contribute up to a certain limit.
