About Xavier

Specializing in .NET development for 18 years, I have had the opportunity to explore a wide variety of business sectors through numerous projects (fintech, accounting, banking, music, museums, ...).

I produce stable and scalable solutions with conscientious respect for the most demanding coding standards and careful selection of the best design patterns.

I can intervene effectively in setting up application architecture and developing complex applications.

I have been partnered with a front-end developer for many years. Our collaboration allows us to efficiently develop full-stack Angular/Type Script/.NET Core solutions.
