Hello,
I have extensive experience in Android framework. I have worked on the apps as well as backends having features like social login, push notifications, firebase, chatting, local to server data-syncing capabilities, etc.
Please provide me further details about the project and the tasks to work upon. Then only I'll be able to let you know the exact cost and time.
Please rest assured about the quality of work. Having worked on almost all types of XML, APIs, integrations and feature implementation, I promise to provide you the best quality work and suggestions from my side as a developer, in terms of optimization of performance and efficiency of the app to serve it's purpose.
Kind Regards,
- Ajay Singh
