Things I am doing or did. In order of recency.
A small experiment run to evaluate the calibration of a modern llm (Opus 4.8) across different confindence levels (80%, 90%) and different questions (partially known and unknown completely).
status → ongoing, blog writeup remaining
Designed collaboratively in a Discord thread with a Fable agent. It runs on Astro and most updates are made using markdown files. Trying to leave a piece of me in the World Wide Web.
An llm-based invoice reader pipeline shipped with a minimal tkinter GUI and supporting SALDEO API sync. It extracts specific chields, validates them (including grounding and IBAN checksum) and exports to SALDEO.
status → ognoing, API connection remaining
A three day lecture on percolation theory (4.5 hours) run during the Maths Beyond Limits Balkans camp for talented high school students from different countries.
A classification model identifying bird species from their flight trajectories, built for a Kaggle challenge. Feature engineering on movement data, a scikit-learn pipeline and result analysis.
A geometry handbook written in Polish for Junior Maths Olympiad students, produced as part of my tutoring work. Theory, worked problems, and the tricks I wish someone had written down for me.
A reinforcement learning engine that teaches itself to play Snake with deep Q-learning. Built in PyTorch to understand DQN mechanics. Also it was fun watching the snake run into walls. A collaboration with Krzysztof Karwik.
A recipe tracking app built by a team of six for the Collaborative Software Engineering Project at TU Delft — Spring Boot backend, JavaFX client. Valuable lesson for working with a team and on a large scale git project.
A mathematics lecture given in Budapest for the Joy of Thinking Foundation on the topic of usage of linear algebra in Olympiad maths. The theory and problem ranged from vector spaces to matricies.
