What I’m doing now
A living page, in the spirit of nownow.com pages: what actually has my attention, updated as it changes — not a static bio.
Engineering the grid
Digitalisation of high-voltage railway traction assets in Frankfurt — IT/OT convergence and security governance for critical infrastructure, at DB InfraGO, since 2024.
Writing the explainers
Reference pieces on grid inertia, IT/OT convergence and why AI is power-bound — written to be cited, checked line by line before they are published.
Revising the books
Two manuscripts in revision: The Renewables Migration (with eleven public chapter proof-engine repositories) and The Orbital AI Compute Roadmap — being rewritten the hard way, claim by claim.
