Bookkeeper by day. Builder by night.
By day I run accounts payable and receivable, payroll, and reconciliations that have to be right. By night I make agent systems, Linux machines, and music software do real work. Either way, I publish the evidence, including the failures.

A Python agent system that writes music for Ableton Live: an intent interpreter, an arrangement planner, a DAW bridge, sqlite-backed memory, and telemetry on every run.
Its first honest audit found the feedback loop was theatre: the planner never listened. That finding, evidence, root cause, and the fix now in build, is the most useful thing it has produced so far.
● PUBLICPYTHON · LINUX · STDLIB ONLY
Socket observation for Linux, rebuilt from /proc first principles instead of shelling out to the tools that already exist, to learn what they actually do.
Hex-table parsing, inode-to-process joins, untrusted-input sanitisation, deliberate SIGPIPE handling, and a test suite that runs against a fake /proc tree. No root. No dependencies.

Tiles mpv windows across an Omarchy/Hyprland desktop for split-screen viewing. Built for my own workstation, useful to anyone's.
A Hammerspoon overlay that brings fluid swipe gestures to macOS Mission Control.
Six-plus years of clerical and financial-office work. The numbers reconcile, or I find out why. That standard doesn't clock out.
Rebuilding MUSE's planner so feedback changes the music, measurably. The build gets written up as it ships, a few times a week, on LinkedIn and X.
Open to bookkeeping, administrative, and customer-operations roles in Sacramento and the Bay Area. Fastest way to reach me: michael@heavener.co.
I'm a bookkeeper and builder in Sacramento. The day job is financial operations: the books, the payroll, the reconciliations. The night work is small systems that do real work: agent software, Linux machines, and the tooling that connects them. Both run on the same standard, and I publish the evidence, including the failures.
Right now: MUSE, the systems underneath it, and a daily fluency practice aimed at junior and apprentice software roles, alongside the bookkeeping and administrative work I've done for six-plus years. Reach me at michael@heavener.co, find the work on GitHub, or the person on LinkedIn.
