BackSpin
BackSpin pays developers while their AI coding tools are busy. As lead engineer I built the editor extension, the CLI, an MCP server and the ad exchange behind them.
WHAT IT DOES
- Detects the moments when Claude Code, Cursor, Codex and other AI coding tools are working and the developer is waiting.
- Shows one sponsored discovery card in that wait, through each tool's own hook, plugin or MCP server instead of wrapping the terminal.
- Scores verified human attention, filters fraud and pays developers a revenue share for it.
- Allocates impressions by share of voice instead of highest bid wins. The allocation algorithm is open source on GitHub.
- Bills advertisers per delivered attention second, with an open ledger of the market.

MY ROLE
Lead Engineer. I lead the system design and the code, from the attention scoring and the bid market to the extension and the website.
