I am a computer science researcher working within Systems and Networking. My current research is focused on the following areas:
-
Utilizing recent advances such as RDMA and Programmable Switches (P4) to accelerate data center system performance
-
Improving techniques for Data Deduplication with encrypted data
-
Analyzing the impact of Networking Failures on large-scale software systems
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 Prof. 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 Prof. 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 develop applications with a variety of languages and tools. 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:

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.
