About Quatalyzer

I’m Bertrand Brelier, founder of Quatalyzer Inc., a data science consultancy based in Ontario, Canada. I help businesses around the world solve complex analytical challenges with tailored, high-impact solutions — without the cost or complexity of building full in-house data teams.

With a PhD in Physics and over 15 years of experience in predictive analytics, pricing optimization, and process automation, I’ve supported global companies in sectors ranging from marketing and retail to healthcare and finance. Whether it’s improving sales forecasting, optimizing procurement, or streamlining manual data tasks, my goal is always the same: to deliver measurable, operational impact through clean, pragmatic, and custom-built solutions.

I work directly with marketing, sales, and data teams to quickly understand their pain points and deliver scripts, models, or decision tools that fit their workflows — whether in Python, SQL, Docker container, or as Windows-compatible applications.

If you’re facing a data or operational challenge where a lightweight but powerful solution could make a difference, I’d love to hear from you.
