Interests
When I'm not securing enterprise infrastructure, you'll find me pushing boundaries outdoors — whether that's defending digital systems, conquering Alpine peaks, or carving through fresh powder.
🔐 Cybersecurity
My passion extends far beyond the 9-to-5. I continuously study emerging attack vectors, explore offensive and defensive techniques, and follow the latest threat intelligence — because in cybersecurity, standing still means falling behind.
🏔️ Alpine Hiking
The Swiss Alps are where I recharge. There's something about reaching a summit after hours of climbing that puts everything into perspective — the discipline, the endurance, the reward. It mirrors the mindset I bring to my work every day.
⛷️ Skiing
From carving groomed pistes to navigating off-piste terrain — skiing is pure adrenaline and precision. Growing up in Ticino surrounded by mountains, it's not just a sport, it's a way of life deeply rooted in Swiss culture.
🇨🇭 Military Service
Proudly serving as a Sergeant in the Swiss Armed Forces. The militia system teaches leadership, accountability, and teamwork under pressure — values that directly translate into excellence in the corporate world.
