About Paul

How I help your organization grow and stay secure

I help organizations navigate the complex intersection of digital identity, cryptography, and European regulation. As a "strategic generalist," I bridge the gap between boardroom objectives and technical reality. I ensure your technological foundation is not only secure but also scalable, commercially viable, and compliant with the latest global standards.

What sets me apart
I bring a commercially strong mindset to every engagement. As Chair of the PKI Consortium and advisor to regulators, I am at the source of emerging standards. This "inside track" allows me to provide your organization with a strategic advantage long before new legislation becomes law.

Core Expertise & Superpowers

  • Strategic Planning: Translating complex governance requirements into actionable technical roadmaps.
  • Post-Quantum Cryptography (PQC): Directing the migration to quantum-safe algorithms to mitigate "Harvest Now, Decrypt Later" risks.
  • Compliance & Digital Trust: Achieving audit readiness for WebTrust, ETSI, eIDAS and other frameworks.
  • Hands-on Executive Leadership: While operating at a strategic level, I remain an active practitioner in Go, Python, and TypeScript.

Engagement Types & Deliverables

I am available 1 to 2 days per week for:

  • Fractional CTO/CTrO Roles: Strategic oversight of digital trust ecosystems.
  • PKI Maturity Assessments: Identifying resilience gaps and implementing crypto-agile remediation.
  • Technical Standards Advocacy: Representing your interests within SDOs such as IETF and ETSI.
  • Product-Market Alignment: Reviewing architectures to ensure they meet both user needs and regulatory trends.
  • Dutch
