Available for new opportunities

Michelle M.
Lefebvre

10+ years in technical roles, 5 years frontend. Enterprise, agency, and consulting. Products used by 22M+ people. Based in Montréal, QC.

I'm looking for my next great team. If you care about what you ship and how you build it, let's talk.

Michelle Lefebvre

A builder by nature

"You'll never know if you like programming unless you try it." When I realized I could build something beautiful in a day, I've been hooked ever since.

I spent over a decade as a CAD Manager and Architectural & Engineering Technologist. Overseeing complex technical solutions and bridging the gap between technical teams and non-technical stakeholders. That foundation of precision, documentation, and cross-disciplinary thinking still shapes how I approach every codebase.

My path into tech was when I attended a tech meetup. It was a panel of 5 ladies who had all taught themselves to code and made career changes. I thought about it for 2 days and decided to try it. HTML done in a day. Day 2 was CSS. When I got to colour I lost 3 days to building colour palettes. Probably stems from my interior design background.

When I discovered that you could build a website in 1-2 days I was hooked. In architecture, you draw for 1-3 years before ground breaks. In web development, you can ship something beautiful in a day.

Three months of self-study later, I was building websites for local small businesses. Larger clients followed. That's where I started working with backend developers and the need to understand the full stack became clear. So I returned to school for an intensive one-year full-stack bootcamp at John Abbott College.

Seven years on, I bring the same instinct I had on day one: curiosity first, craft always. I recently completed the Google AI Professional Certificate and am actively exploring how AI tooling is reshaping the way we build.

Let's work together

I'm open to senior frontend and software engineer roles. If you're building something you care about and need someone who takes the work seriously, I'd love to hear from you.
