01Selected Work

Things I've shipped.

These are self-directed projects. They are where my .NET / C# / architecture depth comes from. My day job at Service Canada was search-platform technical analysis on canada.ca, not .NET development.

Architectural Decision Records lock the scope: no social feed, no public reviews, booking-scoped messaging only. Currently active development — Montréal-first, single-maintainer.

Want to build something together?

I'm looking for a junior to mid full-stack role where my self-directed .NET work and my Service Canada production discipline both matter. Open to remote, hybrid, or on-site (Ottawa-area or relocation). Permanent, contract, or contract-to-hire — happy to chat about any of them.
