As the sole Android developer for an app serving a food chain restaurant, I managed the entire lifecycle of feature development, from refining requirements and estimating tasks to handling releases on the Google Play Console. Additionally, I refactored the entire app using Kotlin and MVVM architecture, which simplified the addition of new features, reduced the number of bugs, and achieved a 99.9% crash-free rate across 300k active installations.

My job was to work on Aitu Messenger. I made a music player for it using ExoPlayer. I used MVVM, MVP, Room, RxJava, Coroutines, GRPC, Retrofit, Glide, and made complex custom views, such as views for recording and playing voice messages.

My first job involved collaborating on various projects, both independently and as part of a team. For one project, I teamed up with another developer for about six months, embracing the concept of pair programming.
