The main project is to build a mobile app with an offline mode which is resilient to different network scenarios. This Mobile apps has to be built with two core capabilities: * Local storage/ database. * Data synchronization. Offline Data Storage and Access: While making the app work offline, the selected developer has to make it so that the app will often need to store data directly on the client’s device. This allows the application to work effectively even when there is no connection. However, using solution such as local caching (cache manifest) and cookies for local data access is an option the developer will have to AVOID. We favor solutions such as SQLite Database or other that can offer the speed and power of a full featured relational database.

Hello, how are you ? I've gone carefully through your requirements with great interests. The offline capabilities are very good solution when the app doesn't to store data on a remote data base, you actual situation can be this one, BUT you should know for example firebase cloud give you chance to persist data on your phone then you access directly . ON android now, There is a new solution called ROOM for storing data locally. This library use SQLite and SQL syntax to fetch and store data . I am very excited to work with you, If you can first contact me and share with me your requirement then we can move forward . also There another solution called Realme . we can talk more .. Thanks

Hello, I have experience in Java and Android app development. Your project sounds interesting and easy enough to be finished within 1 day. I can store data using SQLite as it's mentioned in your project description and avoid using any caching and network solutions. However, I have some questions: 1. How big should be data storage? 2. Do you have any preferences for GUI? Thanks a lot! Ivan Melnyk
