TodayIT & AI consultant · Freelance
From server infrastructure to AI strategy — I cover the full spectrum of modern IT consulting. No generalist mush, but deep expertise in each area.
AI readiness assessment, LLM integration (OpenAI, Anthropic, local models), RAG systems, AI workflow automation and strategic AI consulting.
Architecture, high availability and migration of Linux systems (Debian, Ubuntu, RHEL). Automation with Ansible.
Planning of firewalls, VPN architectures, network segmentation and security audits for SMB environments.
Cloud migration, hybrid setups, monitoring concepts and backup strategies for scalable environments.
Consulting for Contentful, Bynder and similar platforms in a headless context.
Implementation consulting.
Editorial workflows, CMS migrations and structured content architectures for complex web projects.
System selection, digitalisation advice and senior-level technical management consulting.
A fixed monthly volume of hours (8–16 hrs). Predictable cost, reliable point of contact. Ideal as an "external IT lead" without your own IT department. No surprises on the invoice.
Clearly scoped projects with defined scope, milestones and acceptance criteria. Fixed or time-and-materials budget. For migrations, rollouts and implementations.
Short-term support and technical reviews. Billed in 30-minute increments. Minimum booking 2 hours. For agencies that need a reliable tech partner.
I have lived through and helped shape the commercial use of the internet from the very beginning. In 1995, I set up the first HTTP server of the Brandenburg state government (brandenburg.de) and helped build the IT network of the city of Potsdam. After that came stations at the European Centre for Medium-Range Weather Forecasts in Reading, building the web and streaming infrastructure of rbb, and most recently architecting complex digital platforms at Accenture Song — including the sales platform smart.de.
My technical focus areas: Linux and high-availability systems, DevOps and CI/CD, Docker and Kubernetes, Ansible automation, headless CMS (Adobe AEM, AEP, Contentful), network security — and most recently AI strategy and LLM integration. Industries I have worked deeply in: automotive, energy, media, public broadcasting and public administration.
After a long career in large enterprises and public broadcasting, I now offer my expertise as a freelancer — for organisations that need real seniority but do not want to hire a full-time CTO.
My approach: pragmatic, direct, reliable. I explain complex matters clearly, give clear recommendations and, if you wish, implement them myself.
