About Michel

Over a decade of experience with complex IT systems in banking, insurance, and financial services.

Work alone or in a team? No problem!

Do you have pain, no desire, or simply delays when exchanging Tomcat or WebSphere ND certificates? How about automating that?
Avoid SSL/TLS certificate expiration!
Is it possible? Sure! I'd be happy to help you with that :-)

The processing and elimination of disruptions, as well as the coordination and execution of releases, are also part of my responsibilities.

Automation and optimization of processes are my passion!
