About

I'm an IT Infrastructure professional based in Germany with 20+ years of experience spanning infrastructure architecture, cloud services, and security governance. I've built complete IT environments from scratch for international subsidiaries, and I enjoy bridging technical complexity with practical business outcomes. Beyond infrastructure, I build web applications and automation tools to solve real operational problems.
