Hobbies
Outside of engineering systems and breaking them (ethically), I train discipline through physical endurance and combat sports:
- Cycling & Running: Building endurance and mental resilience. I regularly track my activities on Strava.
- Calisthenics: Mastering bodyweight control and functional strength.
- Shadow Boxing: Sharpening reflexes, coordination, and mental focus.
