AI tools, open-source projects, and our first Android game, built by one developer and written up in public.
I'm Geoffery, a software engineer who builds whatever the problem calls for. Sometimes that's a web tool like OnlyBuyForLife, sometimes an open-source project like RuleKiln, and right now it's a mobile game about an office worker who dies at his desk.
Not decks, not strategy docs. Working software. If it's not shipped, it doesn't count.
Every product we build gets a dev log on the blog. The decisions, the dead ends, the wins — all of it.
Tools that are useful beyond our own projects get released as open source, so you can read, run, and improve them.
A web tool that's live today and our first Android game. Here's what's in the works.
A portrait-mode action roguelite for Android
An exhausted office worker dies at his desk and wakes in a collapsing corporate afterlife. Throw keyboards, outrun departments being deleted, and fight down to Executive Management. One thumb, 12–18 minute runs.
AI-powered Buy It For Life product discovery
Stop wasting money on gear that breaks. Our AI surfaces the most-recommended long-lasting products from Reddit's r/BuyItForLife community and enriches them with live eBay listings so you can buy the right thing at the right price.
Code we've released for anyone to use.
A prompt compiler that turns labeled cases into tested, versioned, auditable system prompts. Pay an expensive teacher model once, at build time, to distill task rules; then let smaller, cheaper student models, including local and on-device ones, run the task in production.
It extracts and clusters rules, compiles prompt candidates, grades them against the same cases, and only ships a prompt that passes its quality gates, with a full MLflow audit trail.
No vendor kickbacks here. These are the tools that have earned a permanent spot in the stack.
Open-source game engine with a solid Android export path. It's what our first game is built on.
Typed data pipelines and APIs that behave predictably. The backbone of OnlyBuyForLife and RuleKiln.
Reliable hosting and a Postgres-backed database with auth baked in. Good defaults, minimal ops overhead.
Frontier models where quality matters most, and local models on our own hardware with llama.cpp when cost and privacy matter more.
Dev logs, build notes, and the occasional deep dive.
Feedback on the game, issues on the open-source projects, or questions about anything on the blog are all welcome.
