Full-stack developer building production software with AI-assisted engineering teams. Self-hosted infrastructure, open-source tools, zero cloud lock-in.
// About
I'm also an open-source contributor — I was a committer and PPMC member on Apache Airflow back when it was still an incubator project. These days I channel that energy into building my own things: a pet supplies shop called Hello Best Friend here in Lunenburg, and a growing collection of side projects that push the limits of AI-assisted software development.
What excites me most right now is exploring how structured teams of AI agents can collaborate on real production software — from architecture decisions through deployment. Every project on this page was built that way. Bilingual (EN/FR).

Dory
Operations app for Canadian SMBsThe operations system of record for Canadian businesses that buy and sell physical things. AI parses vendor bills, drives a multi-vendor product catalog ingested from Shopify, email, and Drive, and keeps cost, tax, and a CRA-defensible audit trail clean — with QuickBooks-ready exports. Canadian-first: CAD default, date-banded GST/HST/PST/QST, ITC tracking, and weighted-average COGS that recalculates on every receipt. Role-based team accounts, weeks-of-supply forecasting, and a 21-spec Playwright E2E suite gating every PR.
