About me

Portrait photo of Joseph Henry Passineau

Full-stack developer based in Montréal with 17 years building custom software. I work across the full lifecycle: analysis, architecture, development, DevOps, and UI design.

Currently working at ARIV where I handle everything from the initial client conversation to shipping and maintaining the product. I've worked my way through enterprise SharePoint consulting across major Quebec organizations, a SaaS product at Workleap, and a few years running my own firm.

I got my first computer at 6, started figuring out how it worked on my own around 12, and eventually went to school for it. That curiosity never really went away. I still build things after work because I genuinely enjoy it.
