Profile
Deeply technical, operationally realistic.
I am not a manager who only delegates. I work inside the systems – while still deciding with cost, risk and operations in mind.
In my main role I am responsible for IT operations of a corporate group comprising around 50 companies at roughly 35 European sites. That means multi-company environments, systems grown over decades, shared server and network resources – and very little tolerance for downtime.
Alongside that I have worked independently since 2009, covering everything from network and server projects through video surveillance to lighting control systems in event venues.
- Legacy rather than greenfield Migrating and modernising environments that have grown over many years – without stopping operations.
- Troubleshooting mixed landscapes When Windows, Linux, legacy ERP and cloud collide and nobody can tell where the fault lies.
- Decisions, not buzzwords Technical and commercial assessment, prepared so that management and owners can act on it.
- Responsibility through to operation Concept, implementation, documentation and ongoing support from a single source.
