I'm curious, a problem-solver, and a creator.

Growing up, I spent a lot of my time (probably too much) creating mods for video games and defining new ways to play them with my friends. Despite always being particularly fascinated by computers and technology, I began my university studies intending on becoming a medical doctor. Two years into human anatomy labs and learning about medical ethics, I took an introductory C++ course as an elective and decided to change my trajectory.

Making the transition required an accelerated course load, including summer terms, to graduate on schedule. While demanding, the experience not only reinforced my love of learning, but it also deepened my appreciation for human health and interaction, empathy, and the people around me.

Since obtaining my B.Sc. Hons in Computer Science, I've gained exceptional experience over several years of building highly-available backend and frontend systems for cloud computing and AI inference, video games, and satellite radio.

I love collaborating with and mentoring others; challenging and ambiguous problems; and simple, elegant solutions.

When I'm not building and maintaining large-scale distributed systems, you might find me looking for the next most delicious food to eat, playing a musical instrument, reading, or looking up at the stars.

The Moon The Moon shot through my telescope. Fun fact: toward the top left is the Tycho impact crater. It's about 108 million years old and 85km (53mi) across | XT8 1200mm f/5.9 | 35mm | captured via P3 4.44mm ISO91
Jupiter Jupiter and moons Europa, Ganymede, and Io | XT8 1200mm f/5.9 | 9mm + 2x Barlow | captured via P3 4.44mm ISO91
Saturn Not as detailed as photos from Hubble, but there's something about seeing light reflected by Saturn's rings with your own eyes | XT8 1200mm f/5.9 | 9mm + 2x Barlow | captured via P3 4.44mm ISO91
Pleiades Pleiades / Seven Sisters (M45) star cluster: 100 million years old and about 400 light-years away! | XT8 1200mm f/5.9 | 35mm | captured via P8 6.90mm ISO16340
??? Bonus photo: this ramen no longer exists because I ate it. I really like food.
