01 / Challenge
What needed to change
A live sports product must adapt to different tournament structures and match states while keeping predictions, trivia, statistics, and social features dependable across a mature codebase.
02 / Approach
How I worked
- Built the live Trivia journey across joining, timed questions, results, and leaderboards, along with Team and Player detail experiences.
- Delivered Google Sign-In, report-user and blocked-user handling, AI match predictions, YouTube tutorials, Redux data layers, and API integrations.
- Adapted the app for Euro and World Cup seasons, migrated Firebase analytics, updated native configuration and versions, and fixed knockout scoring, tutorial crashes, and an iOS 14 white-screen issue.
03 / Outcome
The result
Expanded the product's core contest and content experience across multiple football seasons while stabilizing several high-impact production paths.
