Lab Reports
Things I've built — software and process.
Not just code. Some of the work I'm proudest of is a process — a way of working that made a team faster. Each entry says whether it's software or process, and whether AI was a build partner.
Featured Report
Grey Eminence
A native macOS meeting recorder that never joins the call: on-device transcription, speaker diarization, and a Claude-powered memory of everything said.
Records the mic and system audio with Core Audio taps, transcribes both on the Neural Engine while the meeting runs, then re-transcribes with a larger Whisper model after. Claude turns transcripts into summaries, action items, and answers; an interview mode scores candidates against rubrics with evidence quotes.
Other Lab Reports
TCC
An experiment with the tiny pi coding agent that became my daily-driver harness: AWS Bedrock underneath, twenty-five extensions on top, every behaviour mine to change.
MCP servers
A monorepo of Model Context Protocol servers built as facades, not adapters: each tool answers a question I actually ask, with the org's tribal knowledge baked in.
Evalu8
A one-evening Electron app that replaced the Postman collection: a bespoke client for a sparsely documented API, built to explore call evaluations the way I actually wanted to read them.
matthewpurdon.me + design system
This site and the dark, data-forward design system under it: a look distilled from sites I admire, a voice cloned from my own Teams messages, and every page built in three layers.
Technical Evolution (TE) Proposals
A lightweight RFC format for engineering teams — small enough that people actually write them.
