2. Backing Up Running Databases Without Stopping Them

   A Bash container around BorgBackup. BTRFS snapshots give atomic consistency, numeric env vars give multi-target 3-2-1, the loop is sleep not cron.

3. A Physics Practice App for the Hungarian Érettségi

   A static jQuery site I built in high school to drill past exam questions. 659 questions, a decade of past papers, still online and still used.

4. 25 Million UK Property Rows in a Single Rust Process

   Notes on perfect-postcode.co.uk. Every numeric feature is u16-quantised in a row-major array, so filter eval is two integer compares per row.

5. An E-Ink Photo Frame That Sleeps When the House Is Empty

   A Pi, a 6-colour e-ink panel, and a self-hosted Immich library. Photos picked by date and favourites, gated on Home Assistant presence, Atkinson-dithered.

6. A WebGPU Drawing Garden Where Agents Rewrite Your Strokes

   A single-file WebGPU drawing toy. You stroke a colour, agents follow it, and a 3×3 matrix per vibe gives each preset its personality.

7. A 3-Way Text Merger That Never Shows Conflict Markers

   reconcile-text merges Markdown notes from three editors I don't control, with no history. Why git, CRDTs, and diff-match-patch each failed me.

8. A Python Framework Where Doing the Right Thing Is the Default

   My MSc thesis. 33 catalogued ML deployment habits, a decorator-shaped Python API, and a survey of working engineers on which actually got adopted.

9. A 2D Ray Tracer for the Browser, Tuned for the Phone in Your Pocket

   My BSc thesis library. The mobile GPU shaped the architecture: tile-based passes, deferred shading, shaders generated per scene and device.

10. One Game Library, Imported by Both the Client and the Server

    A mobile multiplayer browser game where client and server linked the same TypeScript module. One source of truth, one fewer class of bug.

11. A 50 FPS Game Engine on an 8-Bit Microcontroller

    A handheld game built from the PCB up: ATtiny85V, OLED, IR receiver, EEPROM, 8 MHz 8-bit ALU. 50 FPS floor.

12. Syncing State with an Immutable Trie

    A visual goal tracker whose lasting idea was the sync model: an immutable trie so structural diffs are trivial and only deltas cross the wire.

13. Two Graphs Are Simpler Than One: A Cooling System Simulator

    Live cooling-system sim for a PLC cybersecurity event. Splitting flow and heat into two graph passes kept it cheap and the behaviour believable.

14. Predicting EUR/USD With Hanning Windows

    A weekend frequency-domain experiment that did a passable job on EUR/USD. I would not have trusted it with my money, and I didn't.

15. My Notes: A Markdown App for Android

    A small Android note app built on Markwon. The idea wasn't new; the point was learning a platform that wasn't the web.

16. A Unity City Where Bad PLC Code Made Cars Crash

    A REST-controlled traffic-light sim for a cybersecurity event. Bad PLC code showed up as car crashes, the most honest feedback loop I've shipped.

17. A Colour Grader Where Distance Was the Whole Idea

    Pick a colour, transform every nearby colour as a function of distance. A proof-of-concept grader I built to try one interaction idea.

19. A 3D Voxel Game in C, Built While Learning Pointers

    My Basics of Programming project. 3D platformer in C with SDL 1.2, destructible terrain, time-slowdown powerups, and a great many segmentation faults.

20. A Photo Site That Generated Itself From a Folder

    A Webpack script that turns a folder of photos into a static site with responsive image variants. Mostly here as an excuse to talk about walks.

22. A JavaFX Editor for the Cooling Simulator

    Companion editor for the cooling-system sim. Drag-and-drop graph layout, JSON export, upload-to-backend. Small tool, mattered more than I expected.
