Technology & startups
Architecture that survives growth
Platform architecture, team building, scaling challenges. Venture-backed growth, and what investors look for when evaluating technical foundations.
Industries
Where I go deep,
and where I have lived.
I can work across industries, but I have built particular depth in sectors where strategic and technical work matter most. Complex, regulated, or high-velocity environments where getting it wrong has real consequences.
Sectors
Seven worlds I know from the inside.
E-mobility & connected vehicles
Firmware that outlives the OEM
Embedded Linux, vehicle telematics, OTA at cellular-realistic sizes. I maintain open-source firmware deployed on real vehicles, so I know which patterns actually survive the field.
Public sector & civic tech
Boring infrastructure, built right
Federal archives, council records, open data. I run Quellenportal for the Bundesarchiv and MeinBezirk for civic council documents.
Healthcare & life sciences
Regulated software, shipped
Interim CTO and CPO for medical-device companies. EU MDR and FDA submissions. SaMD, IEC 62304, ISO 13485, ISO 14971, the whole stack from product strategy to technical file.
Retail & e-commerce
Black Friday-grade systems
5× performance improvements. Personalisation engines. Platforms rebuilt to handle 10× traffic growth. When milliseconds compound, rigorous execution wins.
Travel & hospitality
Inventory and reservations at scale
Reservation systems, dynamic pricing, distribution. High-write, integration-heavy environments where downtime has a price tag.
Finance & insurance
Compliance meets velocity
Legacy modernisation, real-time trading, risk and KYC platforms. Innovation that does not put the firm in front of a regulator.
