What I'm looking for

I’m looking to build AI-powered growth and GTM systems where campaign, customer, and commerce data can drive measurable acquisition, conversion, and creative-testing outcomes.

I build AI-powered GTM systems that connect campaign, commerce, and customer data to improve targeting and decision-making. In my independent consulting practice, I created an outbound engine that generated 500+ leads at a 5%+ reply rate and a speed-to-lead system that improved conversion rate by 20%.

At Hermès, I analyzed and optimized international Google Ads and Meta Ads accounts, delivering a 28% increase in ROAS and a 7% reduction in CPC. I also built SQL and Power BI reporting and benchmarking frameworks with 10+ dashboards to turn performance data into clear growth actions.

My experience spans paid media, analytics, creative testing, SEO, CRM automation, and cross-platform GTM workflows. At Challenges, I grew organic traffic by 25% through Google Discover strategy, headline testing, and publishing optimization; at Nice-Matin Group, I supported subscription campaigns and CRM flows for 50K+ subscribers.

I work across Claude, Meta Ads, Shopify, analytics, and creative-generation workflows, combining technical execution with performance-driven marketing strategy. I’m fluent in English and French, with intermediate Spanish, and bring the discipline of national-level basketball and competitive boxing to my work.
