Software Engineering @ UWaterloo
about
Hi! I'm Justin. I'm in 3B SE and I previously worked at
Tesla as a Software Engineer,
where I'm returning this winter.
Right now, I'm writing the last 2 chapters of a short story.

At Tesla, I worked on data pipelines and software for the web. My
intern project involved building an agentic search engine for many
different data sources across the company (think Perplexity or
Notion AI, but for Tesla). I also got the chance to own the
development of a new application for Quality Engineers, which
displays the
genealogy of
parts inside of any Tesla vehicle.
I previously interned at
Zynga Inc. as both a Data
Engineer and Backend Engineer. I worked on data pipelines that
could scale to millions of daily events using tech like Kafka and
Spark. I also built infrastructure that Zynga uses to observe its
large machine learning models in production. Finally, I wrote
Go/gRPC code for low-latency services in
Zynga Poker.
In 2024, I co-founded
Waterloo Reality Labs.
It's probably the coolest thing I've ever done. As Software Lead,
I directed the development of
on-device AI models
for hand pose recognition. As a wider team, we're trying to build
a humanoid robot and
VR headsets from scratch. Our team consists of 30-40 student engineers, and we even hire
full-time interns.
In 2023, I received the top prizes at
Hack the North
and
HackWestern.
I was also previously a Workshop Lead at Hack the North.
In 2022, I began my degree at UWaterloo. I also started my
YouTube channel, which a lot of new SE students seem to ask me about :P
I'm currently the president of the
Software Engineering Society.
I'm a friend of
Socratica, and you can
find me spending my weekends there.
Contact me if you're interested in what I do! I'm especially down
to chat if you're intrigued by the work we do at Reality Labs.
Comms are also always open to SEs who have program concerns or who
are stressed & lost (I've been there too).
