💫 The Story Started as a broke philosophy student in Kyiv who taught himself Python to automate his part-time job at a logistics company. Accidentally built an ETL system that saved them $50K annually. Philosophy degree? Abandoned. Data engineering career? Born. 💭 Philosophy "Data engineering is like being a digital architect, plumber, and fortune teller all at once. We build the invisible infrastructure that powers tomorrow's innovations, fix the pipes when they break, and predict what will break next. It's the most beautifully chaotic job in tech." 📍 Currently: Building the future of financial data while chasing the perfect work-life-travel balance 🎪 Fun Fact: Once fixed a critical production bug while stuck in a Romanian cable car during a thunderstorm. The WiFi was surprisingly good.
