Mobile applications are no longer an option for companies; having a presence on cell phones (or any mobile device) is important to strengthen the relationship with customers, especially for the banking industry. This is why an Android developer is the right option when hiring a nearshore expert.


Now why an Android developer? Well, the logical answer to this is in the numbers. According to a study by Statista, Samsung and Xiaomi (both companies with Android operating systems) occupy first and third place respectively in the list of best-selling phones by the end of 2023, so it is necessary to have an Android expert if You want to please the majority of customers or users.


An Android developer will bring expertise to the project of developing an application for a banking company, but you must be aware of the key skills they must have so that said application is functional, in line with current trends, and satisfies even the most demanding user.

  • Back-end development: Knowledge of back-end technologies to interact with servers, APIs, and databases securely. This might involve using frameworks like Spring for Java or Ktor for Kotlin.
  • API Integration: Experience integrating third-party APIs, such as payment gateways, authentication services, or banking APIs, to enable features such as account management, transactions, and notifications.
