Présentation
A technology leader with over 15 years of experience in designing secure and scalable cloud architectures. I have led complex digital transformations that have delivered measurable ROI: a 40% reduction in cloud costs (FinOps), a 60% improvement in time-to-market, and ISO 27001/SOC2 compliance achieved without operational friction.

My philosophy: Security is not a hindrance but a growth accelerator when managed with agility and intelligence (e.g., integrated into product design, ...).

Key achievements:
→ Migration from an on-premises platform to the cloud, incorporating a vision and strong security enhancements
→ Multi-cloud architecture (GCP/AWS) supporting 30M+ users with a 99.99% SLA
→ FinOps strategy that saved €3M annually while doubling capacity
→ DevSecOps framework reducing vulnerabilities by 85% in production
→ Team of 25+ engineers transformed into a center of technical excellence

Expertise: Security Awareness - Cloud Architecture • FinOps • Product Security • Platform Engineering • Team Leadership • Business Strategy

Passionate about building and integrating technology solutions that combine performance, security, and cost-efficiency.

My approach: #LeverageBusiness #BuildSecure #ScaleSmart #LeadWithPurpose
