What skills should an Android developer have to create a mobile app for the banking industry?

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.

Developing a mobile app for the banking industry requires a combination of technical skills, industry knowledge, and attention to security and compliance. Here is a list of key skills an Android developer should have:

• Android Development: Proficiency in Android development, including Java or Kotlin programming languages, Android SDK, Android Studio, and familiarity with Android design principles.
• UI/UX Design: Ability to design intuitive and easy-to-use interfaces, complying with Material Design guidelines and ensuring a seamless user experience.

• 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.

• Testing and Debugging: Proficient in testing methodologies, including unit testing, integration testing, and UI testing, using tools such as JUnit, Espresso, and Mockito. Also, the ability to debug and troubleshoot efficiently.
• Version control: Familiarity with version control systems like Git to manage changes to the code base and collaborate with other developers.
• Compliance and Regulation: Knowledge of banking industry regulations and compliance standards, such as PCI DSS, GDPR, and local financial regulations, to ensure the application meets all necessary requirements.
