About Ulrich

PHP developer for over 15 years, I have been working with Symfony since version 1.0. I have had the opportunity to work on all its versions and maintain projects by managing framework version upgrades.
I have mainly worked on B2B SaaS applications but also on some high-traffic e-commerce sites.
I have technically mentored many developers to help them improve their skills.
My field of expertise does not stop at development; I administer servers, I implement software architectures based on asynchronous programming and NoSQL, on projects with high legacy or from scratch, I evangelize best practices within teams.
