About Rémi

Expert Cryptography, PKI & Post-Quantum Transition – 20+ years.

I help CTOs, CISOs, and public-sector leaders make long-term cryptographic decisions in highly regulated environments.

My expertise focuses on PKI modernization, eIDAS trust services, and post-quantum readiness, where wrong technical choices can create regulatory failure or long-term security debt.

I intervene on:
- Cryptographic architecture & PKI modernization
- Post-quantum risk assessment & migration strategy
- eIDAS / ANSSI compliance & audit preparation

Background: Former Director of Technology at an eIDAS-qualified SaaS provider, former Head of Engineering in post-quantum cryptography.

I typically work with banks, telecom operators, government agencies, and critical infrastructure operators on high-impact, high-risk projects.

    Expert PKI, PQC, eIDAS & Trust Services
    September 2025 - Today (9 months)
    I help organizations build secure cryptographic infrastructures and prepare for post-quantum challenges.

    Recent Projects:

    SKEDL (French Ticketing Platform)
    - Designed and secured the cryptographic infrastructure for ticket emission
    - Implemented integrity verification and certificate-based authentication for issued tickets
    - Pilot hybrid post-quantum cryptography for secure ticket issuance

    ✓ Cryptographic Inventory Platform
    Cryptographic asset discovery and quantum-safe readiness (CBOM standard)

    QPKI: A Go-based X.509 PKI toolkit supporting hybrid post-quantum certificates. Designed to prototype and evaluate post-quantum PKI integration in existing environments.
    QLAB: A hands-on training environment to learn PKI fundamentals and practice post-quantum migration scenarios. Allows teams to test, validate, and understand quantum-safe certificate deployment.
    Together, QPKI provides a technical playground for post-quantum PKI experimentation,while QLAB turns it into hands-on learning.
