Montréal, QC 45.50°N 73.57°W local

I build backends that hold up under load, and products people actually use on a Friday night.

Backend lead at Catena Logistix, writing mostly Go. After hours I ship ChaloCity and DevDrafted, take photos wherever I land, and work the grill at a steakhouse.

Resumes as code. Write YAML, get a typeset PDF, then tune it to a job post with Gemini.
