Senior Full Stack Engineer · Jul 2022– Jan 2024
Implemented a responsive React frontend integrating WebSockets and Server-Sent Events for live odds, picks validation, and dynamic leaderboards. Content and game configurations were managed via DotCMS for editorial workflows.
Users needed a low-friction way to engage with sports betting concepts without full account creation or complex onboarding, while maintaining real-time responsiveness during live games.
Built a real-time UI using WebSockets for bi-directional updates (picks, timers, session state) and SSE for scalable broadcast streams (scores, odds, events). Modular React components handled game rounds, streaks, and rewards. Integrated DotCMS to power content, promotions, and regional compliance messaging.
Supported 90K+ participating users within the first month of MVP launch, with reduced latency for in-game updates and improved content agility via CMS-driven configuration.
