Terminal & TUI developer · Rust, Go, TypeScript · local-first AI tooling

I build tools, scripts, and terminal experiences — from ASCII art to LLM-powered automation. Currently focused on elegant TUI tools, OpenCode/agent tooling, and AI integrations that run on your own hardware.

A beautiful terminal Kanban board built with Rust and Ratatui.

Terminal chat app in Rust.

Wayland-native clipboard history manager for GNOME. No X11, no Electron.

Terminal skill manager for opencode: browse, preview, validate, edit and install skills.

llama-deck: keyboard-first TUI and CLI to discover, configure, launch, and monitor a single managed llama.cpp llama-server instance, with presets and live telemetry.

Personal, Git-native knowledge library — a Markdown archive with a Hugo static site as the view.

Things you can open and use right now — no install. The full index lives on the Tools page.
