Hi, I'm

Staff Engineer & Tech Lead

Building distributed architectures with .NET and Azure

About me

I'm a software engineer with over 12 years of experience, specialized in the .NET ecosystem and distributed architectures on Azure.

I currently lead technical teams as a Staff Engineer at Ecovadis, where I drive the migration from a monolith to microservices in the sustainability sector.

My day-to-day revolves around Domain-Driven Design, CQRS, and building scalable, maintainable systems. I firmly believe that good architecture is the one that enables teams to deliver value sustainably.
