About Me

At the start of my career, I actively contributed to the development of the Lutece CMS Core for the City of Paris and other stakeholders, laying a strong foundation in public sector digital solutions.
I also worked as a Java/JEE developer on web applications for the French Public Sector, focusing on robust and efficient systems.
With over 10 years of experience in Adobe Experience Manager, I specialize in designing scalable architectures for corporate and e-commerce websites, primarily for luxury brands and major retailers. I am recognized as a Subject Matter Expert (SME) in AEM Assets-based DAM architectures.
As Adobe Expertise Director, I support the New Business team by creating proposal architectures, delivering demos and Proofs of Concept, and responding to RFPs with technical solutions and precise estimates. I present and defend our vision during client pitches.
I have extensive expertise in Agile Software Development, SCRUM methodology, version control systems, Java, and DevOps tools, combined with strong technical, analytical, logical, and communication skills.
