Designing secure, sovereign, and scalable cloud architectures — and occasionally jumping out of airplanes at 4,000m. 🪂

Whether at work or in my free time, I thrive on teamwork, high altitude, and continuous learning:

• 🪂 Skydiving (Parachutisme): Literally spending my weekends in the clouds! Jumping out of planes taught me rigorous preparation, risk management, and staying calm under pressure — skills that translate surprisingly well to production cloud incidents.
• 🏀 Basketball: Huge basketball fan & player. All about court vision, fast transitions, and collective execution.
• ⚡ Sports & Tech Enthusiast: Always exploring new technologies and pushing limits both on the court and in the terminal.
