Simon Lavallée
ing., B.Eng.
I turn complex technical problems into clear, defensible decisions — in court, in the boardroom, or in a product.
About
I'm a computer engineer from ÉTS (#5047738, Ordre des ingénieurs du Québec), operating at the intersection of technology, law, and strategy. Since 2010, I've led Firme H2E, where I act as a digital forensics expert for lawyers, courts, and companies facing litigation involving digital evidence.
In parallel, I spent nine years at Banque Nationale du Canada, most recently as Product Owner (PO) on strategic data assets including Snowflake. This dual life — independent expert by night, bank intrapreneur by day — gave me a rare vantage point: understanding technology through both the lens of legal risk and product innovation.
Bilingual, pedagogical, builder. I code, analyze, testify in court, and train lawyers. Passionate about quantitative finance and stock markets since earning my financial engineering degree. What drives me: solving real problems with rigor and creativity.
