Developer & Solo Founder · St. Louis, MO
I build and ship products solo. No team, no funding, no excuses.
Every project below is real and shipped — live sites serving users, native apps running every day.
| Project | What It Does | Tech | Scale |
|---|---|---|---|
| Swarm | Native SwiftUI BitTorrent client — a fast, modern answer to Transmission's dated UI. Wraps libtorrent behind an Obj-C++ bridge; three-pane layout, live throughput graphs, SOCKS5 proxy with a real TCP and UDP test, fail-closed "require a VPN or proxy" guard, phone web remote (works anywhere via Tailscale), Sparkle auto-updates with delta patches. Signed, notarized, sandboxed. | Swift, SwiftUI, Objective-C++, libtorrent, Sparkle, Network.framework | Shipped 1.1 · DMG + Homebrew |
| Flipside | Sampler/sequencer modeled on the classic 16-pad hardware-sampler workflow — chop samples and flip them into beats, driven by a Midi Fighter 64 + nanoKONTROL. 16 sequences × 8 banks, Chop mode, 16 Levels, Pad/Knob FX, Song mode | Swift, SwiftUI, AVAudioEngine, CoreMIDI | Full hardware-sampler workflow on a 64-pad grid |
| DL4 Conductor | Turns a Mac into the brain for Line 6 DL4 MkII pedals over USB-C MIDI — a tempo-locked delay conductor with LFO-swept feedback, a MIDI-learn grid controller for dual loopers, and a phone looper remote | Swift, CoreMIDI, USB MIDI | Drives 2 pedals + 64-pad grid, phone remote |
| MF3D Cockpit | Midi Fighter 3D arcade controller turned real-time mission control for parallel Claude Code sessions — 9 session pads with live status LEDs (thinking / waiting / done / failed), one-touch approvals, hold-to-talk dictation, self-learning tab mapping via the accessibility API, drag-drop web configurator. Spans two Macs over an ssh reverse tunnel | Hammerspoon (Lua), Swift, CoreMIDI, Python | 64 RGB pads · 4 banks · 2 machines |
| Chop Shop | Mashup IDE for Midi Fighter 3D/64 controllers. Chops any song into 1/8-note finger-drum pads by stem family with smart per-family slicing, beat-quantized pad editor, LED light-show builder with drag-to-paint + image-to-pixel-art, Ableton .als export |
Swift, SwiftUI, Core Audio, CoreMIDI, Demucs | 64 pads live, 128-color LED control |

- Programmatic SEO — I build sites that generate thousands of indexable pages from structured data
- Native when it matters — for real-time audio, MIDI hardware, and torrent engines, I go Swift + SwiftUI, not Electron
- Ship daily — I'd rather ship something imperfect today than something perfect never
- Full-stack, full-ownership — Design, frontend, backend, infra, DNS, SEO, code-signing, notarization — I do all of it

Ship it. Get feedback. Fix it. Repeat. Perfect is the enemy of live.
I don't wait for gatekeepers. Websites rank on Google and serve real users; Mac apps ship as signed, notarized downloads with their own auto-update pipeline — no app store required.
Currently building the next thing. Always.
