Design the data model

The data model is the structure of the data that will be stored in the backend. This involves defining the entities and relationships that will be used to represent the app’s data. For example, the data model might include entities such as users, accounts, transactions, and payment methods. 

Implement business logic

The business logic is the set of rules that govern how the app operates. This includes rules related to user authentication, account management, transaction processing, and payment processing. The business logic is implemented in the backend using programming logic and database queries. 


The front-end of the app is the user interface that users interact with and is responsible for seamless user experience. It includes elements such as the app’s design, layout, and navigation. It is important to ensure that the frontend is designed to be intuitive, easy to use, and secure.

Choose a tech stack

The next step is to choose a fintech app development framework for the frontend. Popular options include React Native, Flutter, and Ionic. The choice of framework will depend on factors such as the app’s requirements, development team’s skill set, and performance needs. 

Develop the user interface

Once the user interface has been defined in the Design stage, the next step is to develop the user interface using the chosen development framework. This involves creating individual components, screens, and navigational flows, and ensuring that they work seamlessly together.
