Software
Local-first apps, browser tools, and privately run AI systems. I learn by building, ship software that works, and care about how a thing is structured, not just whether it runs.
Christopher W. Mahl
Independent software, built with intent.
I'm a self-taught developer using Fedora who makes small, private tools that do one thing well, and I've spent years working busy dining rooms, a different sort of real-time systems work.
What I do
Two disciplines, one standard.
Hospitality
Several years of front-of-house and bar experience. Fast, efficient, and genuinely good with people even when the room is full. Service at a high level is systems work with a human face.
Selected work
Small tools, built to be owned.
Threadkeeper
A Firefox extension that exports your ChatGPT, Claude, and Gemini conversations, individually, in bulk or selected, as clean Markdown or JSON, featuring full-text search across every thread.
View on GitHubAlgoZap
A Firefox and Chrome extension that catches manipulative rhetoric in social-media posts, explains the tactic in plain language, and drafts three styles of reply. Live on both add-on stores.

About
The short version.
I'm Chris, a developer and hospitality professional based just outside Buffalo, New York. I like building small software tools, local AI systems, and browser extensions that are well-made and genuinely mine which respect the person using it, and work that holds up.
Self-taught, systems-minded, and particular about craft. Open to development work, collaboration, and good conversation.
