What I actually do
No waving with Gantt charts and disappearing. Rather touching the code, architecting and refactoring together with my team - necessary to build what makes sense and works.
- Experienced in public clouds, on-prem infrastructure, including air-gapped systems - on virtual machines and in containers.

- Securing and automating the entire SDLC - IDEs, CICD pipelines, change management, deployment…
