As an android developer, my goals are to help you create streamlined processes that free you up to do what you're awesome at, while I handle the programming stuff. I've consulted with dozens of small businesses and have started, run, and sold businesses of my own, so I know first-hand the challenges of wearing every hat in the building. I can help make your life easier by taking some of the load off of you.
Here is my github profile : https://github.com/azizur-rehman/
I use Kotlin as my main language for the development. My expertise in android , I am keen in using the android's architecture components - MVVM, Navigation Component, WorkManager, LiveData, Coroutines I have also used almost every product of Firebase generally including Database, Firestore, Auth, Cloud Functions, etc Apart from that, for APIs I use retrofit with my own handy generic kotlin extensions and for recyclerViews I use my own extensions.
I have also worked on POS based software that deals with Card Payment, Card Reader Payment and other related stuff to POS. Currently, I am the leader developer of the POS app running on PAX A920 Payment Terminal.
