Cover image for Invoke lets you (and agents!)
Invoke lets you (and agents!) create custom commands for any macOS application, then bind those to shortcuts. Everything happens in less than a millisecond, making shortcuts feel like they're natively part of the app they're for. Agents can use Invoke to inspect applications and interact with them, then build repeatable workflows using tiny, dead-simple JavaScript snippets.

Cover image for 5–20K DAU. Real-time multiplayer games.
5–20K DAU. Real-time multiplayer games. Thousands of players betting simultaneously, results resolving live, shared chat. Drove a full frontend rewrite from jQuery to Vue. Wrote a provably fair system — lets players cryptographically verify outcomes were determined before bets. Worked across the entire product: frontend, backend, design, community management, marketing. Separate contracts for ETH payment infrastructure, backend maintenance, and API documentation.
