I build correctness-critical systems. Two of them right now: real-time audio plugins, and a governed context backend that AI agents read from over MCP, read-only and approval-gated. Founder and Lead Engineer at Bellweather Studios.
I spent a decade making records before building the tools for it. Grammy-nominated, a few billion streams, a Billboard #1. The audio work is an extension of having done the job.
A real slice of the Bellweather platform, not a demo: the framework-neutral audio modules, lifted out and re-licensed under Apache-2.0. The headline is a from-scratch loudness meter (BS.1770 / EBU R128) you can run a real conformance suite against. It ships with the RT-safety primitives the plugins lean on, and Barometer as a source-built JUCE reference. The whole thing builds clean-room, behind an enforced public-surface boundary so nothing from the paid tree leaks in.

Real-time audio: native C++20 plugins across VST3, AU, AAX, CLAP. Lock-free, and nothing gets allocated on the audio thread.
Governed context backend: Prisma/Postgres systems of record that are the single source of truth for clients, human and machine. Authority is data, not inference. Every mutation is audited. OAuth on MCP, in production.
Platform: the build and test infrastructure that keeps all of it honest. Drift gates, shared kernels, and far too many tests.
