About Thierry

Senior C++ architect — 21 years designing systems where failure is not an option.

Launching an ambitious C++ project and looking for someone to take charge of the architecture, challenge the existing, and deliver quickly with minimal supervision?

Refactoring a hindering legacy system, developing from scratch, turning a POC into a product, or acting as Tech Lead to guide a team: this is my domain.

I particularly enjoy the phases where everything is still open: laying the architectural groundwork, transforming a vague idea into a high-performing system.

━━━ MY DOMAIN ━━━
• Aeronautics & Simulation — Thales Training & Simulation (5 years): audio system refactoring for flight simulators, C++ ARINC 429 and ED247 libraries in production
• Real-time Industrial Vision — industrial cameras, OpenCV, 60 FPS / 12 ms pipelines
• Critical Systems — Technical Design Documents (TDD), testing, traceability

━━━ WHAT I DO ━━━
• C++ Architecture (all versions), Qt/QML
• Design from scratch and legacy refactoring
• Tech Lead / R&D technical expert
• Computer Vision (OpenCV, GPU)
• Real-time Audio (MaxMSP + C++ controller)
• POCs, audits, industrializable prototypes

━━━ WHY CHOOSE ME ━━━
• Top 5% worldwide in C++ (LinkedIn, 728,000 candidates)
• 21 years delivering complex systems in production
• AI-augmented development — 3x velocity in architecture and POC phases, without compromising quality
• Proactive: I challenge before coding to prevent technical debt upstream
• End-to-end autonomy: specs, architecture, code, documentation, delivery

━━━ HOW I WORK ━━━
Fully remote or hybrid, minimum 2-month missions, quick start. I thrive in environments where technical decisions are made quickly and where I'm trusted with the methodology — I commit to concrete deliverables, not hours spent.
