What I built
ShippedJul 2026A platform where each company gets its own pool: everyone’s picks visible to the group, a live leaderboard, a chat and an admin panel for the results. From idea to production in under two weeks.
Three companies used it live during the 2026 World Cup. MaaliMetrics, a sports data company, ran theirs with their own brand and match analysis.
The boring parts got fast. The hard parts stayed hard.
