I help organizations in defense and healthcare design and operate secure cloud platforms and Confidential Computing solutions.

Focus: remote attestation (AMD SEV-SNP, Nitro Enclaves), data-in-use protection, cloud security architecture (AWS, Azure, OpenStack), security reviews and compliance (ISO 27001 / BSI / NATO-aligned architectures).

• Advisory / Architecture — Strategic guidance, architecture reviews, security patterns and decision memos.
• Project Delivery — Hands-on design and implementation (IaC, attestation flows, enclave enablement, controls and guardrails).
• Security and Compliance Readiness — Gap analysis and remediation plan for ISO 27001 / BSI IT-Grundschutz; evidence prep for audits and stakeholder reviews.
• Fractional / Interim — Part-time Security or Cloud Architect for defense and healthcare programs: governance, leadership and vendor alignment.

Day rate: from €750 / day (excl. VAT).

Availability: typically up to 1–2 days per week or in dedicated project sprints.

Engagements can be delivered on-site or remotely across the EU, subject to prior arrangement.

Contracts are issued under German small-business regulation (Kleinunternehmerregelung), with no VAT charged in accordance with §19 UStG; for EU cross-border services, the reverse-charge mechanism applies.

• Defense: multi-cloud data sovereignty, secure data sharing and federation.
• Healthcare: privacy-preserving analytics and enclave-backed research pipelines.
• R&D: HPC with enclaves, confidential AI/ML workloads, evidence and benchmarks.

Share a brief on scope, timelines and stakeholders. I typically respond within one business day.
