CasePulse
A case-theory stress test for litigators. Every allegation in a pleading mapped against the evidence bundle — supported, contradicted, gap, unaddressed — and every finding sourced back to the verbatim line. Modelling the dispute as a graph made weak claims and contradiction clusters visible where flat retrieval misses them. The judge abstains below its confidence threshold rather than guessing. On the challenge’s synthetic demo bundle it scored the pleaded case 28/100 and found 8 of 13 allegations contradicted by the claimant’s own evidence. Built with three others over a weekend; I handled the engine.

PixelRiot
Europe’s largest generative-AI hackathon. I built and ran registration, the submission pipeline, automated mail and the public site, and coordinated $600k+ in API credits across the tool partners. The November 2025 edition opened at the American Film Festival in Wrocław; the 2026 Vienna edition is in preparation.

Cross-attention for autism diagnosis
Bidirectional cross-attention between fMRI and sMRI for Autism Spectrum Disorder classification, across 871 ABIDE subjects and eleven Transformer architectures exploring different tokenisation strategies. Cross-attention reached 69.9% against a 63.5% single-modality baseline. The thesis spends as long on evaluation-methodology gaps in neuroimaging as it does on that result.

HyperGnome
An open-source GNOME Shell extension bringing Hyprland-style dwindle (BSP) tiling to GNOME. Per-workspace window trees, animated focus borders, configurable gaps, and a native Gtk preferences UI, with GSettings schemas and keybinding conflict detection. One codebase covers GNOME 46–49 on both Wayland and X11. Sole maintainer.

GenSnitch
Right-click any image and ask whether it was AI-generated. Reads Content Credentials, provenance signals and the metadata patterns generative tools leave behind — entirely in the browser — then produces a shareable report with JSON export. Deliberately honest about the answer: no evidence found is not the same as real.

Study Notes - Open MSc AI Lecture Notes
A public, searchable vault of my MSc Artificial Intelligence notes at the University of Amsterdam: lecture notes, concept wikis, and exercises for Reinforcement Learning, Information Retrieval, and Recommender Systems. Built with Quartz and published at notes.swasilewski.com so the notes are useful to other students, not just to me.

Can you murder a robot? - Polityka Article
Published article in Polityka, one of Poland's leading newspapers, exploring the philosophical and ethical implications of AI personhood. Examined questions of robot consciousness, harm, and legal frameworks for non-human entities.
