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.
