A PHP/Symfony developer who grew up alongside companies of every size: early-stage startups, a near-unicorn, and everything in between. Before the code, I ran a kitchen brigade, where execution under pressure doesn't forgive improvisation.
One conviction stuck with me: craftsmanship isn't a luxury, it's what keeps the code standing when the company changes scale. Today I'm Tech Lead Architect at a Québec fintech, working on legacy applications you're not allowed to break.
