Software // Agentic developer // Open-source builder

I turn messy technical problems into thoughtful software people can actually use.

Selected work

Released public work. The problem comes first; the implementation is there when you want it.

Things I cared enough
to finish and ship.

01 / Selected systemReleased

Engram

AI agents need durable context, but opaque vendor memory makes that context hard to inspect, review, move, or own.

A human-owned, file-first memory protocol that keeps agent knowledge in plain Markdown, under review, portable through Git, and usable across agents.

TypeScript · Node.js · Markdownv0.0.28

02 / Selected systemReleased

Aevra

AI assistants can reason about local work, but giving them direct machine access without a clear authority boundary creates unacceptable security and audit risk.

A local MCP execution gateway that lets AI clients work with files, commands, Git, browsers, desktop apps, and upstream MCP servers under explicit capability policies and human approvals.

TypeScript · Node.js · Reactv1.1.3

03 / Selected systemReleased

Markdown Explorer

Markdown is an excellent interchange format for agents and repositories, but large Markdown workspaces become awkward for humans to browse, search, and read.

A private, local documentation experience that turns Markdown and MDX folders into searchable workspaces across VS Code, Chromium, and desktop apps.

TypeScript · React · Tauriv1.6.8

04 / Selected systemReleased

QuotaShift

AI coding tools expose different quota windows, balances, profiles, and reset rules, forcing users to repeatedly inspect separate apps and account states.

A desktop dashboard, tray app, and overlay that monitors provider usage in one place and supports safe account switching where the provider workflow allows it.

TypeScript · React · Tauriv1.1.3

05 / Selected systemReleased

Markdown Them

Documents usually arrive as Word files, PDFs, spreadsheets, or slides, while notes, repositories, and developer tooling work best with plain Markdown.

One converter engine that turns a dozen document formats into Markdown on your own machine, available as a browser app, desktop app, VS Code extension, and Node.js package.

TypeScript · React · Electronv1.3.2

How I build

Simple code.
Clear boundaries.
Useful outcomes.

I like software that earns its complexity. That usually means understanding the real problem, keeping boundaries explicit, and choosing fewer dependencies when fewer will do.

I build AI tooling, developer tools, and local-first software—and I contribute to open source when I can see it making work or life better for someone else.
