Back to original languageAbout Felix
As a freelance Senior System & Cloud Infrastructure Consultant, I help corporations and medium-sized businesses operate complex IT environments performantly and securely. My path led from 2nd-level support at BASF through hardware roll-outs to founding my own IT service provider – today I combine hands-on experience with strategic foresight.
What you can expect: analytical strength, high quality standards, and rapid implementation – from troubleshooting to complete cloud transformation, ready for remote or on-site deployment.
