Pierre-Henri Fricot

Launching a product, taking over legacy systems, or facing technical limitations? I offer CTO as a Service to frame, audit, or rebuild the technical foundations of your product, and support your teams.

Principal Engineer & Architect, co-founder of Yundera (self-hosted sovereign cloud) and Aptero (XR for corporate training and education). 15 years of software architecture experience, from secure embedded systems at IDEMIA (JavaCard, cryptography, identity documents, biometrics) to multi-region distributed cloud.

🤝 How I work

‣ Rigor inherited from secure embedded systems (Common Criteria certified products at IDEMIA): firm milestones, weekly written updates, decision traceability, mission completion.

‣ Cross-functional vision, from silicon to cloud: development, product, operations, security, management. I empower teams to become autonomous through pair programming, architecture reviews, and documentation.

🛠️ Typical missions

‣ 360° Technical Audit

Architecture, technical debt, security, or performance diagnostics. Deliverable: actionable report with quantified priorities. 5 to 10 days.

‣ Part-time / Transitional CTO

Technical leadership, stack arbitration, recruitment, implementation of best practices. 1 to 2 days per week, 3 to 6 months commitment.

‣ Cloud, on-premise, or sovereign architecture

Design of distributed platforms (microservices, mesh, security), legacy system refactoring, or scaling initiatives.

‣ Technical training and coaching

Software engineering courses at Coding Factory and CY Tech. Mentoring leads, code reviews, team upskilling.

🎯 What sets me apart

A unique background covering highly secure embedded systems (smart cards, biometrics, encryption) and modern distributed cloud. I've built, not just advised: two SaaS products in production, clients like L'Oréal, Aéroports de Paris, and KPMG, and active contributions to the European XR4ED and UnitedXR Europe consortia.
