Chris Tsang

Founder @ SeaQL / Rust Engineer / Open Source Advocate

Hi! I am Chris, originally from Hong Kong, now living in the UK. I am a Rust Software Engineer. I am the founder of SeaQL.org, best known for developing SeaORM .

Life Story

Open source is my north star. I published my first computer graphics library on GitHub when I was 18 years old. At 27 years old, I started Vision Cortex, best known for developing VTracer . Later I discovered a niche in the Rust ecosystem, so we pivoted and started working on SeaQL.

SeaQL won the OpenUK Awards 2023  in the Software category.

Mission

I believe in open-source software. Collaborating on open source development represents humanity’s most remarkable technological progress. Open-source encapsulates our collective wisdom and embodies our shared commitment to tackle problems beyond our individual capacities - whether those of a person or a company.

Creating open-source software isn’t easy, and funding an organisation can be hard. I continue to search for better ways to fund, build and grow open-source projects, and to invite more people into this community.

Faith vs Reality

Maintainer burnout is a real issue. As a maintainer I felt the grind everyday. I rely on a glimpse of hope in which the industry is becoming more supportive to community-driven open source (as opposed to corporate-driven); and that we can eventually stumble upon a way to make open source sustainable.

Research Work

I am not in academia, but I am glad to have been cited for my work. My interest includes computer graphics, computational geometry, real-time programming, compilers / debuggers and software engineering techniques.
