Hi! I'm a student at the University of Waterloo studying software engineering. I have an interest in large scale distributed algorithms and infrastructure for data analytics. I also enjoy working with low level systems.

Experience

GoogleMountain View, California
Software Engineering InternSept 2018 - Dec 2018
  • Built large-scale, robust data analysis pipelines to serve machine learning models for improving ad asset selection and composition.
  • Streamlined and extended pipeline for selecting and enhancing top performing AdGroups, and increased total network revenue by 0.2%.
  • Developed dashboards to evaluate performance of models and discover insights for further improvements.
datacoral IncSan Francisco, California
Software Engineering InternJan 2018 - Apr 2018
  • Scoped out, architected, and implemented highly scalable materialized views in Redshift using Kinesis Data Streams, DynamoDB, and Lambda.
  • Used timelabel tags to represent the state of underlying data, update materialized views when dependencies get updated, and handle schedule and view definition changes.
  • Built critical APIs and migration scripts to launch a web application for monitoring materialized views and data pipeline performance.
YelpSan Francisco, California
Software Engineering InternMay 2017 - Aug 2017
  • Explored and evaluated solutions for better client-side JS error reporting.
  • Implemented and rolled out infrastructure to process over 25 million errors every month to over 20 services.
  • Modernized build pipeline and built tooling to migrate services from Google Closure Library to ES6 and Webpack, and from npm to yarn.
  • Helped develop infrastructure and tooling to migrate services to React, including server-side rendering of React components.
Ivy GlobalToronto, Ontario
Software Engineering InternNov 2015 - Sept 2016
  • Led the development of a bubblesheet scanner and grader using convolutional neural networks, and custom image processing algorithms to process blurred, tilted, and imprecise images.
  • Developed an ASP web application that displays SAT scores and statistics for mock exams in real-time.

Projects

kademlia-dht-rsPersonal Project
GitHub RepoRust, Distributed Systems
  • A flexible implementation of Kademlia, a distributed hash table.
  • Used strict parallelism to efficiently send RPCs to probe nearby nodes.
inSightGreylock Hackfest
Hackathon ArticlePython, C++, Unity, Tensorflow
  • An interactive AR headset that uses both machine learning and custom image analysis algorithms to display information about the user’s point of focus.
  • Applied gaze tracking to enable full control of headset via eye movement.
  • Used Bing and IoT technology to control home appliances and learn about surroundings in an intuitive way.
