I am working as an iOS mobile app developer to help Ruangguru develop and build their iOS mobile app. The features that I have taken part on so far : - Gamification : giving a reward for each completed objective. - Social Media : internal social media feature that will allow the user to share their post, achievement, reward, etc. - Student Report : it will provide some key charts about the user’s performance and their progress in studying with Ruangguru - Brain Academy : it helped the Brain Academy subscriber to do their pre-session test and post test by using their smartphone. It also helped them to manage their private schedule with their master teacher. - Maintain assessment related features such as quizzes, tryouts, question bank, etc. To enable these features in offline mode, Core data was utilized to store the data. For the last few months, my whole iOS team and I have been revamping the code base. Replacing the aging MVC pattern with the MVVM pattern along with RXSwift and declarative UI.

During the time periods, I sometimes worked on mobile app development projects in my spare time for both iOS or Android as side hustles. During the time range, I had 3 major projects that I built using React Native. One of them had been submitted to Google Play Store and two of them were an internal system therefore they were not published to Play Store. Here are some highlighted features that I used for those projects : - Firebase RealTime Database - Firebase Push Notification - Google Sign In Auth - Google In App Purchase - Google Map SDK
