The LNB platform is the official digital hub for the Dominican National Basketball League: live scores, standings, player stats, and season calendars for one of the country's most passionate sports audiences. The hard part was the real-time layer. Live games push constant updates, so I used MQTT over WebSockets instead of polling, with Redux coordinating multiple data streams so simultaneous game updates never lag the UI. The trickiest piece was the subscription lifecycle, keeping connections clean as users move between games without leaking memory during long live sessions. Styled Components kept styling co-located for fast iteration under deadline.
