The Lab
Built fast.
Things I build, fast — experiments and 0-to-1 builds to pressure-test agentic development. Some are products, some are just proof. The point is velocity and range.
Marko
A Typora-class desktop Markdown editor — WYSIWYG, live-preview, and raw in one window, with 13 themes, Mermaid, math, and one-click Pandoc export.

Claude Desktop MCP for Ven
An MCP server that lets someone who's never opened a terminal run a developer's API by just talking to it — type a sentence, fire off a long-running job, get back a polished, billable PDF. No docs, no SDK, no “let me loop in an engineer.” Plain English is the interface; agents call agents over MCP.

Pretty Keyboard
A MIDI companion for Logic Pro — your laptop keys become an expressive instrument with hand zones, scale-aware key lighting, and a chord engine. Creates its own virtual CoreMIDI port, so Logic just sees it.

NI Kontrol S88 MK3 — LED hack
Reverse-engineered the lightguide on Native Instruments' flagship keyboard. The community had been stuck for 2+ years because LED control killed MIDI — I found the missing command that restores it, enabling live Synthesia-style key lighting with chord coalescing.

gex.me — NFC cards
A tap-to-connect NFC business card with a customizable landing page and a cross-platform contact-card download. "Tap to connect — a first impression worthy of you."

Weekend agents & tools
A few smaller builds, each spun up over a weekend to test an idea.
- Scheduler — A Calendly-class scheduling app, built in a weekend.
- Job-application agent — An autonomous agent that fired off 500 applications — agentic browser automation at scale.
- VC outreach tool — Agentic investor outreach — sourced and personalized at scale.
Landing pages
Production sites I've shipped
Built with Next.js, Tailwind, and agentic coding — most in a single sitting.
