About Damien

I design and develop custom web platforms for entrepreneurs and SMEs who want a real business tool - not just a website.

For 8 years, I've been supporting my clients from idea to production: architecture, development, process automation, and AI integration where it adds value.

Some concrete results:
+800k users on the developed platforms,
+€7M in revenue generated for my clients.

My preferred areas: SaaS platforms, internal tools, custom e-commerce (Magento), workflow automation.

Do you have a platform project to build or a process to automate? Contact me to discuss it.
