My Philosophy: Optimizing Humans, Not Just Systems

"I believe in optimizing humans, not just systems. I do 7-day water fasts to build mental discipline. I work on BMW engines because troubleshooting complex mechanical systems parallels debugging distributed architectures. I race cars to understand calculated risk-taking under pressure. I play soccer because leadership is the ultimate team sport. I follow the Pareto Principle in all I do and believe in Time Revolution. Every day is Another Day in Paradise."

Everything connects - whether it's my engineers hitting 30% velocity gains or pushing my own limits daily. Excellence is a system, not an accident.

Mental Discipline

7-day water fasts build the resilience needed for impossible technical challenges

Systems Thinking

BMW engine troubleshooting parallels debugging distributed architectures

Calculated Risk

Racing teaches risk management and split-second decision making

Team Leadership

Soccer develops the collaborative mindset essential for engineering teams

Pareto Principle

80/20 thinking in everything - from gaming rig builds to cleaning dishes by hand for agility practice

Universal Energy

Meditation, gratitude, family balance - blessed with amazing wife Agnieszka and two kids: Damian (CTO) & Anna (Future Actuary)
