John Wilson
Lead developer at Sessionwire: AI, real-time audio and video.
I'm the lead developer at Sessionwire. I set the architecture through two rebuilds to over 37,000 registered users, write code, and review every change before it merges. From 2024 to late 2025 I led a full-time developer. I planned and assigned the work. I also run index9 (opens in a new tab), a small Mac software studio. Kelowna, BC.
I worked in audio for ten years. Audio is signal flow: what goes where, in what order, and what happens when a stage fails. So is software, and so is getting models to build it.

AI and real-time work
- Call rebuild
- WebRTC calls on Daily, rebuilt in seven releases in July 2026, each with a switch or a rollback ready. A dropped connection rejoins on its own. In 8,143 calls from July to October 2026, nobody was left waiting alone. The largest call had 216 people join, 169 of them at once.
- Triage
- Read-only tools an agent uses to find why something broke in Sessionwire. The tools line the timestamps up across the sources, and can look at everything and change nothing.
- Search
- Finds music by how it sounds and people by what they do. CLAP and MERT run on Modal GPUs, and people search merges keyword and vector results by rank. Running it costs Sessionwire under $30 a month.
- Remote control
- Control someone else's computer during a Sessionwire call, once they click Allow. Keys and the pointer go directly between the two computers over a WebRTC data channel, up to about 60 pointer moves a second.
- Firelight
- A YouTube channel of sleep stories. Claude Opus 5.5 writes, Kokoro speaks and Qwen-Image draws on Modal GPUs, and a vision model checks every still. I built the pipeline and check each episode before it goes out.
also
- 8track
- A Tascam Portastudio 488, an 8‑track cassette recorder, rebuilt for the browser. Open the studio and press play.
- Whetstone (opens in a new tab)
- A Mac app from index9 that rewrites your rough prompt for the model you picked.
- Windrose (opens in a new tab)
- A Mac app from index9 that controls the fans on Apple Silicon Macs.
- Canadian bank notes
- The Bank of Canada's main bank note series, front and back, from 2011 back to 1935.
