Ruby Lu

Hi, I'm Ruby!

I study computer science at the University of Waterloo. My primary focus lies in backend engineering and distributed systems, but I'm increasingly fascinated by the infrastructure required to support large-scale AI systems.

When I'm not staring at a terminal, you'll probably find me indulging in my creative side through art, whether it's drawing, painting, or digital art. I also like to make an unnecessary amount of Spotify playlists and consider myself to be a movie enthusiast (with a soft spot for the horror genre), having watched and logged 0 films (0 this year) on Letterboxd so far. I've recently started learning guitar too.

This website, which I’ve poured many hours into, is an attempt to capture my growth as a developer as well as the passions that fuel me outside of tech. Thanks for stopping by!

Past & Present

This past fall term, I interned at Amazon Web Services (AWS) in Seattle! I worked with the DynamoDB Global Tables team to break down regional obstacles for infrastructure tooling. It was super interesting to learn about the challenges of maintaining a massive, high-performance database.

In winter 2025, I interned at Hatch in their Niagara Falls office, where I was introduced to the complexities of hydropower optimization. I worked on improving the efficiency of hydropower dams and explored the use of machine learning for predicting water inflow, which bridges the fields of engineering, sustainability, and software.

In summer 2024, I worked on enhancing desktop applications and automating systems for YM Inc., a Toronto-based retail company that operates fashion brands across North America.

I've been reading a lot of Peanuts comic strips recently, so enjoy these gifs from A Charlie Brown Christmas (1965)!
