Math-minded data lead. Curious about bioinformatics, genomics and neuroscience. Appreciate aesthetics and the fine art of meta-irony. Cologne expat 🇩🇪.

DE/Medical procedures. At home, this would typically be done under anesthesia off/on. Here I stayed fully awake with only a painkiller. With my background in CS, my #defensemechanism is to reduce stress to numbers and signals. But the human side of the system caught me completely off guard.

Theory is only as good as its execution. I approached #TOGAF after years of working in Data Architecture leadership roles. What surprised me: practical experience was.... distracting! It made the exam harder, because real-world judgement and architectural thinking aren't always the same thing.

Day 736. The last time I spoke #German was with my cat's veterinarian. About six months ago. I forced myself to learn a few medical terms I don't even know in English. There was always an easier option: they could speak Polish, I could answer in Russian, and somehow we'd understand each other.

Having spent years in large financial ecosystems, I keep expecting f(x). Input. Rules. Output. Call it a professional bias. ​ Relationship-driven systems still feel like an odd duck to me. Family-owned companies, however, often run on something else entirely: tradition, trust, personal networks.

6yrs in amateur #swimming. Good enough lung capacity, 1+ min breath holds. Yet, breathing every 5-7 strokes pushed me to panic 😲. It wasn’t an O₂ issue. The brain is more sensitive to rising CO₂ than falling O₂. The alarm goes off early 🚨. The fix was counterintuitive: continuous (!) active exhale.

They glide horizontally, leaving behind a massive, exploding trail of white mosaic tiles that simulates a rush of air bubbles. At the top, a small text reads: "Artwork by Alexey Lazar, shared with permission".

Michael Lewis’s The Undoing Project is less about economics and more about the structure of human judgment. Tversky and Kahneman showed how people systematically misread probability and uncertainty, often relying on what memory retrieves most easily rather than on statistical reality. #booksky
