I self-studied programming during secondary school but stopped afterward. I resumed learning programming since Jun 2020. Currently using Java and Android Studio to write some simple apps. My first app: Ruler-caltor was released to Google App Store (https://play.google.com/store/apps/details?id=com.simpleruler.g) and Huawei App Gallery (https://appgallery.huawei.com/#/app/C102640913) in early August. My second app: Worksheet Genie was released in early September. https://play.google.com/store/apps/details?id=com.hwstudio.worksheetgenie.g https://appgallery.cloud.huawei.com/ag/n/app/C102810299
