Hard things,
done right.
I'm Jakub, an engineer and founder from Warsaw. I like problems where almost right is the same as wrong: detector software at CERN, model inference at TSMC, risk systems at Point72, and two companies of my own. On the research side, I work on explaining what neural networks actually listen to.
Now
Autumn 20262025–
EnergyScope | Co-founder, CTO
An AI energy operator for Polish factories. I lead the edge hardware, the forecasting platform and the battery dispatch behind it.
2025–
Point72 | Software Engineer, Risk Technology
Production systems across risk, quantitative research and trading, where latency and correctness both matter. Joined as an intern, full-time since January 2026.
2026–
Warsaw University of Technology | M.Sc., individual studies
With Prof. Maria Ganzha. Digital twins of real industrial sites, with explanations built into every decision the twin makes.
