About Denis

I’m a French cloud architect and startup builder with 25 years of hands-on experience
turning complex ideas into production-ready solutions. Across three startups and multiple
consulting missions, I’ve led teams and customers from first design to live deployment.
Fully AWS-certified, I’ve delivered scalable architectures and high-impact workloads—with a
constant focus on performance, cost optimization, and user value.
I thrive in agile, collaborative environments where we listen, iterate fast, and measure
success when the customer says: This is exactly what we needed!
