Platform Migration
Virtualisation and cloud migrations, target architecture, cutover planning, support through to handover. Typical triggers: licensing changes, consolidation, cloud exit, hyperconverged refresh.
ENGINEERING BY TOBIAS RATSCHKOWSKI
I build, migrate and automate IT infrastructure. For 30 years.
Services
Where I support companies.
Infrastructure Architecture
Platforms built to last for the years ahead. Compute, storage, network, identity — designed to work together rather than grown side by side. With sovereignty, scalability and operability in mind.
Automation & Operations
Infrastructure-as-Code, GitOps pipelines, monitoring stacks. So platforms don't just stand up but stay reproducible when requirements change.
Software Development
Tools, interfaces, small applications — wherever off-the-shelf software doesn't fit or a gap needs closing. Focus: Python, Go, Bash, REST APIs.
Advisory & Second Opinion
Architecture reviews, migration assessments, tool selection. For teams that need an experienced outside perspective before an investment decision is made.
Projects
