🏦 My specialty? High-criticality transactional systems: financial, trading, payment systems. Where every failure has a measurable cost and industrialization is not an option.
🛠️ Need an embedded technical lead for the long term, or a targeted intervention (audit, training, consulting)? I help your teams master their end-to-end delivery: Craftsmanship, CI/CD, IaC, observability, AI agents.
🚀 Experience forged through several ambitious transformations at Betclic, AXA, Ayvens: contexts under strong operational constraints, where reliability is at the heart of the challenges.
🚨 Seasoned on-call engineer: observability and resilience are design requirements, not late fixes. Metrics, monitors, and SLOs are integrated from the first sprint.
💎 Hands-on technical leadership, pursuing a culture of sustainable quality and reliability within teams. And delivering with the help of the best AI tools available.
📍 Available in the Paris region, or remotely with occasional travel.
