I'm William Blais,
I build thoughtful software for complex systems.

I'm a software developer based in Montreal. I enjoy building software that feels thoughtful, reliable, and genuinely useful.

I'm especially drawn to complex products with lots of moving parts: distributed systems, cloud APIs, background workers, data flows, backend architecture, telemetry, and the kind of frontends that make all of that feel simple.

I like taking messy, heterogeneous problems and turning them into clear abstractions, maintainable systems, and products people can trust. Most of my work lives at the intersection of product and engineering, and over the years I've worked across SaaS products, analytics, automation tooling, and cloud-connected hardware from early ideas through launch.
