About

I am Markus Wernig, an IT professional with over 20 years of experience in enterprise IT projects. I have got a very broad background and experience in IT, which ranges from software engineering to network security and system engineering/administration.

For over 15 years now I have worked primarily in software engineering, from full-stack to appliance, from network automation over PKI and cryptography to database-heavy workflow applications. Before that, I was mainly active in network security.
I have worked alone and in agile team settings. As lead engineer I am comfortable comunicating on executive levels as well as with technical staff and end-users.

I am not, however, a typical 100%-only-developer. Based on my extensive experience in various fields I would describe myself rather as an allrounder with a strong suit in software engineering and security .
Here are some of the technologies I have a work record with:
Java/J2EE, SQL, Angular, Kotlin, HTTP, SOAP, X509, S/MIME, REST, Perl, PHP, JSON, Spring Boot, Firewall, Checkpoint, Forcepoint, VPN, Proxy.

Interested? Please do not hesitate to get in touch.
