I worked as an Android Developer on Yulys, a production job search and recruitment application. I contributed to both job seeker and employer experiences, developing and maintaining Android features using Kotlin, MVVM, Hilt, Retrofit, Firebase, and FCM. My responsibilities included REST API integration, authentication flows, job search and filtering, application features, push notifications, UI development, debugging, testing, and resolving production issues. I also worked on Android releases and updates for the Google Play Store. This experience gave me practical experience working with a real production codebase, backend APIs, different user flows, device-specific issues, and maintaining reliable Android applications.
