I build local-first tools. They run on your own machine, at a footprint you can measure, and they don't phone home.

Mostly Rust and Python on a CPU-only laptop, which turns out to be a useful constraint. It forces you to find out what things actually cost instead of assuming the hardware will cover for you.

hidforge holds an exact click rate from 10 to roughly 10,000 per second and idles at 0% CPU. It learns whatever a button actually emits rather than assuming a button number, because side buttons don't arrive on a predictable channel and some never reach the OS at all.

AirLock strips API keys, passwords and PII out of text before it reaches an LLM. A CLI you can pipe or hang off a pre-commit hook, plus a browser extension that catches the paste itself. Entirely local, zero network calls, which is rather the whole point of a tool for not leaking things.

Alife grows micro-organisms that learn to survive within their own lifetime, no generational hand-waving, on a single CPU core.

mochi is a cat that lives on your desktop, watches you work, and expects to be fed.

anicli-rpc puts whatever you're watching on your Discord profile, live, by sitting between ani-cli and mpv without patching either of them. Sub or dub is deduced from the audio track's language tag, because ani-cli picks one and then never tells the player which.

Cadence is a to-do app built around the more interesting question: why you stop opening to-do apps.

Learning cybersecurity properly, rather than by tutorial.

Reading an unreasonable amount of Win32 documentation as a side effect of hidforge: Raw Input, HID report descriptors, and exactly how much a QueryPerformanceCounter spin loop costs you.

Local IPC, lately. Discord frames its messages with an 8-byte header, mpv speaks line-delimited JSON, and underneath both it is named pipes on Windows or Unix sockets on Linux, which are far less interchangeable than they look.

Before hidforge there was autoclicker: 53 clicks per second, non-adjustable, AutoHotkey. Most of what I've built since has been an argument with that.
