Matthew Newman

Designer and systems builder. I make local-first developer tools, coding-agent workflows, and software that connects to the physical world.

I'm interested in making complex systems understandable and controllable: clear interfaces, durable context, reviewable changes, and a way back when something goes wrong.

My background spans motion graphics, graphic design, UI/UX, and frontend development. These days, that work extends into engineering-document automation, agent tooling, 3D printing, and interactive electronics.

Mostly Python, with TypeScript and C# where they fit. Portfolio: a 3D line-art star map. Not actually an astronaut.

Selected projects

  • apu: Audit and manage coding-agent instructions through reviewable plans, transactional changes, and rollback. Local-first, with a deterministic core.

  • clici: A small Windows tray utility that removes unwanted margins from copied CLI output while preserving meaningful indentation. Built to fix an everyday annoyance.

  • masq: Composable persona profiles for Claude Code. Stack, reorder, and scope voice, style, and workflow preferences without rewriting the underlying setup.
