I build software for live production, and I run a handheld video rig for shows.

Apps

Tools for the people running shows

CyberDeck for Companion

A Bitfocus Companion surface on a phone or tablet.

Registers with Companion the way a Stream Deck does, shows live button state, and sends presses straight back over the LAN. No accounts, no cloud.

  • iOS
  • iPadOS
  • Android
Download CyberDeck on the App Store Get CyberDeck on Google Play

CueStack

Cue points, timecode, and show control on an iPad.

Mark cues on an audio track and replay any section on demand. Generates SMPTE LTC and speaks OSC and MIDI, so a media server chases the iPad.

  • iPadOS

4:20

SMPTE LTC timecode reader and generator.

Plug into the line and read lock, rate, drop frame, direction, and level. Generate clean LTC at any rate from 23.976 to 30 over the same connection.

DeckHand for CyberDeck

Operator surface for productions that run CyberDeck.

A tech lead publishes a role from CyberDeck Pro: the exact buttons an operator needs and nothing else. The operator scans a code and runs the show.

SnapDeck for Companion

Never lose a show config.

Keeps a versioned history of every Bitfocus Companion configuration change, shows what changed in plain terms, and restores a known-good config from the menu bar.

  • macOS
Coming soon

The Total Venue

Crew-sourced venue specs for touring and production.

Loading docks, bus parking, power, rooms, and local crew numbers, contributed by the people who work the buildings. Works offline and syncs when it can.

I am building this one for my dad, a working video programmer who has spent a career on the road.

Live shows

Synchronized handheld screens for the stage

Identical iPads or phones, carried by performers or set in a grid, playing as one timecode-locked display over Wi-Fi. I have run it at the American Music Awards, the Mnet Asian Music Awards, an auto show, and a commercial shoot. You bring the devices, I bring the software and run the show.

Credits, how it works, and what I need from you

Who is behind this

I am a developer in Sacramento, California. I write native iOS, iPadOS, macOS, and Android software for people who work in live production: timecode, cueing, control surfaces, and the tools around them. The apps above are published under Upload Studio Ltd.

Between 2011 and 2018 I built and ran a rig of synchronized iPads and phones for televised performances, an auto show, and a commercial. In 2026 I rebuilt its software from scratch, and I am available to run it again.

Travels worldwide. Rates on request.
