## Projects

### FreeChat
AI coding workbench — an agent that ships code in its own VM
A SvelteKit AI coding platform where every conversation provisions its own BoxLite microVM — a pi agent pairs with you inside it, streaming reasoning, tool calls and diffs as it works with bash, read, write and edit tools. GitHub OAuth with anonymous sessions, conversations persisted in Postgres, per-user concurrency caps. Its agent-side counterpart is Ompdeck, my cockpit for the same pi coding agent.
Tags: typescript, svelte, llm, agents

### Muamua
Self-hosted streaming hub for sports, movies, series and anime
A SvelteKit streaming hub unifying three upstream sources behind typed server-side fetchers — live and upcoming sports with a source-picker player, TMDB-powered movies/series/anime with season and episode pickers, and multi-search — self-deployed on my 10-service homelab stack through automated GitOps.
Tags: sveltekit, typescript

### One Tool
Internal operations platform for TV One
A role-based internal platform that cut four manual tools to one — staff run shifts, loans, campaigns, and admin from a single phone-first dashboard, with full audit trails for charity compliance and one-click reporting.
Tags: svelte, sveltekit, postgres

### Moneyshot
Agent-run content campaign platform — idea to Instagram, measured
A cockpit CLI running the whole Content Creation Chain as an agent-drivable pipeline: research → write → produce → distribute → measure → learn. First campaign: 45 videos driven end-to-end — JSON scripts rendered to 9:16 MP4s through headless chromium + ffmpeg, published via Instagram's official Content Publishing API, with real performance flowing back into a self-recalibrating playbook.
Tags: typescript, cli

### Instat
Turn a content channel into an audiobook, end to end
An agent-drivable CLI that turns a content channel into an audiobook — four pipelines in one binary: Instagram reels transcribed on GPU Whisper, YouTube captions, agent-authored book drafting, and self-hosted vLLM-Omni narration to finished MP3s, all resumable against a SQLite ground truth.
Tags: python, llm, cli

### Ompdeck
A browser cockpit for the pi coding agent
A browser cockpit for the pi coding agent — live streaming transcripts, a full composer with slash palette and @-file mentions, session management and inspection tooling, optional per-project microVM sandboxing. Same cockpit school as FreeChat: FreeChat drives chat models, Ompdeck drives the agent.
Tags: typescript, svelte

### ZenNotes
Keyboard-first local Markdown notes with Vim motions, diagrams, and MCP integration
A local-first Markdown notes system: keyboard-driven editing, Vim motions, Mermaid diagrams, and MCP integration so coding agents can read and write the vault. I contribute upstream — the daily notes, habit tracking, and agent ledger on this machine all run through it.
