ABOUT

Industry-grounded product marketing for technical markets

I have spent my career translating technical products, customer needs and market shifts into product strategies, launches, sales tools and commercial opportunities across manufacturing, packaging and financial services.

Alongside my HEC Paris MBA, I evaluate LLM outputs through Outlier. This work deepens my understanding of model quality and failure modes; my professional foundation remains in product strategy, launches, sales enablement and commercial execution.

I bring industry context, customer insight and field execution to technical go-to-market problems.
