Specializing in .NET, I can also assist you with any other technology.

My main strength lies in complex projects, where I translate business and regulatory requirements into specific model and architecture designs.

In addition to my technological leadership, my finance expertise allows me to discuss directly with product teams and end-users of our application. I can convey and explain to development teams the business logic behind each new feature.

Beyond my role as team tech lead, I designed the platform's architecture, introducing the latest versions of the .NET framework (v.8, 9, and 10) and implementing a microservices architecture and an Angular frontend.
