About Maxime

Expert in Conversion Rate Optimization (CRO) and e-commerce customer journey optimization, I support brands and retailers in the sustainable improvement of their digital performance: increasing conversion rates, revenue, and customer satisfaction.

With over 8 years of experience in demanding e-commerce environments (retail, omnichannel, international), I have managed and deployed data-driven CRO strategies, combining behavioral analysis, A/B testing, UX research, and customer feedback exploitation. Accustomed to managing large volumes (more than 70 experiments per year), I intervene from issue detection to production deployment and performance monitoring, with a clear objective: to generate measurable business impact.

As a freelancer, my ambition is to become a strategic partner for e-commerce and digital teams, capable of:

- Quickly identifying growth levers across the entire purchase funnel,
- Prioritizing high ROI actions,
- Structuring an effective CRO roadmap,
- Supporting teams in skill development and continuous improvement.

My approach is pragmatic, results-oriented, and user-centric, with a strong command of CRO and analytics tools (A/B testing, behavioral analytics, customer feedback, steering dashboards). I undertake both one-off missions (audits, recommendations, tests) and long-term support to establish a culture of continuous optimization.
