iOS Developer

MozzartBet•  May 2017 - Present

Became the first iOS developer at MozzartBet. I developed the iOS app from scratch. My responsibilities included developing new features and maintaining the existing codebase. Implemented a live bet, which needs to be updated in real-time for each live game. The app has thousands of users and is growing daily. Reduced the network requests that have a lot of in-app caching for features that work offline. Implemented features such as sports betting, lucky6, virtual games, and animations, making the app more attractive to users. Organized the app by modules, allowing developers to collaborate easily and making it simpler to visualize dependencies between features. Interviewed candidates for the iOS position and mentored new employees. Managed, coached, and delegating tasks to other iOS developers.
