I'm mobile app developer going freelancer to work on my own projects.
I've successfully developed my own apps and published them.
I prefer Java as my main programing language.
I've successfully implemented various features and libraries during my developments (e.g. Room & SQLite database, Google Sign In, Game Play Services, Glides, GSON, recycleView with Livedata observer, Custom surface view for android canvas game, etc ).
If i hit hard wall i usually keep on trying until i find the way because there's always a solution.
