I now work on distributed databases at Salesforce.
I have recently (2022) defended my PhD from the School of Computer Science at the University of Waterloo. I was advised by Khuzaima Daudjee and was a member of the Data Systems Group.
Generally, my research interests lie in the intersection of distributed systems, databases, and machine learning. I am particularly interested in building adaptive and distributed data systems. My thesis was on the design and development of adaptive data storage and placement in distributed databases.
I received a Bachelor of Computer Science degree from Waterloo in 2016, with a focus on bioinformatics.
Projects
Physical Design within Distributed Data Systems: Modern data systems exist within a cluster of servers, with data distributed across the cluster. Therefore, how data is placed and accessed is critical to application performance. My research focuses on building adaptive data systems that make intelligent and dynamic physical design decisions improve performance. I have applied these techniques in distributed database systems (MorphoSys and DynaMast), HTAP databases (Proteus) and erasure coded storage systems (EC-Store).

Experience
Salesforce
I am a Researcher and Senior Member of Technical Staff at Salesforce. I research, design and implement techniques to improve the performance, scalability and efficiency of Salesforce's distributed database.
I worked on two different infrastructure teams during my internships (2015) at Facebook.
On the Data Infrastructure team I worked on the next generation data warehouse system. I helped improve operational workflows by building a custom log search tool for distributed debugging. I additionally worked on a shared memory file transfer between the client interface and the storage interface.
On the Service Infrastructure team I worked on service discovery and the internal ZooKeeper system. My work focused on moving service discovery from a daemon process to a service itself. In the process I modified the Thrift compiler to provide transport level request caching.
Palantir
As a Software Engineering Intern (2014) at Palantir I prototyped a web application that allowed users to collaborate during investigations within the Palantir web applications. The application allowed users to directly share the state of their investigations as a first class citizen. I also worked on the maps application within Palantir.

Awards
I was awarded the Cheriton Distinguished Dissertation Award for my thesis.
I was named a Distinguished Reviewer at VLDB 2023.
I was previously supported by a NSERC CGS-D scholarship and a Facebook Emerging Scholar award.
Teaching
I was a TA for CS 454 (Distributed Systems) in the winter of 2017, 2018, 2019, 2020 and the summer of 2018. In these offerings I gave guest lectures on erasure coded storage systems. I also helped develop a new assignment on distributed file systems, which is described in our WatDFS SIGCSE paper.
