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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

My First Real Project: LEDs Driven by an FFT
A Raspberry Pi music player that drove RGB strips through MOSFETs. The first thing I started and actually finished.
