WOD Pro League
A global functional-fitness competition platform with real-time leaderboards and live score submission across 120+ countries.
01//the problem
Competitive fitness is global and simultaneous — thousands of athletes submitting scores at once while everyone watches the leaderboard move. That's a low-latency, high-concurrency problem that has to feel instant no matter where you are.
02//the approach
A serverless AWS Lambda + S3 backend keeps cost proportional to load, while Redis and Socket.io drive low-latency live leaderboard updates. Flutter mobile apps and a React web app give athletes and organizers a shared, real-time view.
03//what I built
Real-time leaderboards
Redis + Socket.io push score changes live to every athlete.
Serverless backend
AWS Lambda + S3 scale with demand, not against a fixed server bill.
Global score submission
Athletes across 120+ countries submit and verify scores in real time.
// the impact
12,778 athletes, 8,567 scores submitted, live in 120+ countries.
// let's build yours
