I'm Siyu (David) — a Senior full-stack developer based in New Zealand. I've been building web products for about a decade, mostly figuring out how to make things work well, look right, and not fall apart at scale.
Currently at IDEXX working on API-driven products, and leading engineering at MageBinary on the side. I like teams that ship fast and care about the details.

something together.
I'm always open to interesting conversations — whether it's about a project, a collaboration, or just to say hi.
