# about
I write software that works and doesn't make the next developer hate you. Full-stack: Go and Java on the back, Angular on the front, desktop GUI apps, CLI tools, data pipelines. I've modernised legacy systems, shipped client platforms, and processed large-scale data. I care about the actual problem, not just the ticket.

burrow
TUI-based developer automation tool. Schedule tasks, build pipelines, and run your entire toolchain from a single terminal interface. Config-driven via TOML — no scripting required. Features run history, a task catalogue, built-in scheduler, and pipeline support. Currently at v0.1.5.
waymark
Custom scripting language for text-based games. Waymark provides a purpose-built syntax for defining scenes, choices, and branching narrative logic — with a full parser written in Go. Includes a programmable interface so developers can embed and drive the runtime from their own code.
towers
Browser-based digital implementation of Towers — a fictional card game from Brandon Sanderson's Stormlight Archive. Designing custom spatial mechanics that reject grid-based movement in favour of relational positioning, with a shared central deck and a Go backend communicating over WebSockets. Includes a custom board-state encoding system (GEN) for compact, serialisable game state.
