Side projects, hobby builds and smaller client work. Private repositories are marked as such. The code is not public, but the description is honest about what it does.
My everyday engineering work is at Zelifcam. Larger engagements go through them. Everything on this page is separate. Side projects, hobby builds and smaller client work of my own.
Web applications rendered on the server, mostly Grails, htmx and Postgres, built to work on a phone and to keep working when the connection does not.
Timelines assembled and corroborated by the people who were there. You build a spine of what happened and invite the people who remember it; where accounts disagree, the disagreement becomes part of the record instead of being flattened away.
A multilingual PWA for planning training workshops worldwide, built to keep working when the connection drops. Coordinators, trainers, field partners and guests share one secure place for schedules, personnel, travel documents and messaging.
Booking and client management for a boat excursion business in Roatán, Honduras. Built on a declarative architecture of one controller and one data service, over Postgres full text search and pgvector.
A PWA built for a phone first, for a Christian school. Announcements, calendar, files, prayer wall and messaging for families, plus studios, attendance, grades and badges on the staff side.
A music streaming server you host yourself, for your own library. Adds genre browsing, one click genre playback, shuffle and installable PWA support on top of Black Candy.
A learning management application for Korean language study, with hand rolled server sent events over Servlet async and Postgres full text search.
Club management built for a phone, for Awana leaders. Attendance, scripture progress and QR check in, so club night runs on less paperwork.
Things that run where I actually work. Rust and Python, no browser required.
A digital audio workstation that lives in the terminal, written in Rust. 8 synthesizers, 18 drum kits, 1,275 patches, a plugin system, and zero allocations in the audio path. Runs in the terminal or as a desktop app.
A face, a voice and a pair of eyes for a model you already pay for. Local neural speech, local wake word and transcription, and a camera that recognises the people you enrol. Runs on a Jetson Nano or a Raspberry Pi.
A chess club that lives in your terminal. Ten computer personalities, 5.8 million puzzles, 62 interactive lessons and online game rooms. No browser, no Electron, works over SSH.
A maintained revival of SpaceVim after its original author archived it. The same modular distribution built in layers, for Vim and Neovim, cleaned up and kept working the same way on both editors.
Search Soulseek, queue downloads and watch transfers without opening a browser. Ships a single binary that works as both a scriptable CLI and an interactive TUI.
An SSH connection manager that runs in the terminal. Keep your hosts organised and connect from a TUI instead of hunting through config files.
Create and play animated or static ASCII art in the command line, in colour or monochrome. For roguelikes, screensavers, TUIs and animated logos.
Models and datasets.
A personality preservation system. It trains a model on how one particular person actually talks, using LoRA fine tuning over their own conversations, so what comes back sounds like them rather than like a chatbot. Started years ago as RememberMe and rebuilt from the ground up.
The Universal Repository of Flagged IP Addresses. A free, openly accessible dataset of real network attacks that grows and updates itself hourly, with visual breakdowns of where the traffic comes from.
What the work above and the day job have run on. Grails and Groovy most days, but the problem picks the tool.
