The mobile app will be pretty easy, just need to use some native library to display list of pictures.
And for backend service we can use a Tomcat server for the REST APIs.
Will take a max effort of a month.

Ensuring that users are who they claim to be before granting access to the application. Common methods include username/password, biometrics, or OAuth.
Determining what actions and resources a user is allowed to access or modify within the application. Authorization ensures that authenticated users have appropriate permissions.
Storing frequently accessed data in a cache to reduce the need to fetch it from the original source repeatedly. This improves performance and reduces latency.
Considering and testing scenarios that are at the "edge" or boundary of expected input conditions. These are often situations that may not occur frequently but can have a significant impact when they do.
Implementing the core features and functions that define the primary purpose of the application.
Tracking and analyzing the sequence of user interactions within the application. Click stream analysis helps understand user behavior and optimize the user experience.
Writing and executing tests that validate the smallest units of code (functions, methods, or classes) to ensure they work as intended.
Testing the overall functionality of a specific feature or the entire system. Functional tests verify that the application behaves correctly according to specifications.
Creating scripts or automated tests that can be run to validate various aspects of the application's functionality. Automated testing helps catch regressions and ensures consistent behavior.
Developing separate versions of the application tailored for different operating systems (e.g., iOS and Android) using platform-specific development tools.
Utilizing shared code libraries or frameworks to streamline development, improve consistency, and leverage existing solutions for common tasks.
Implementing practices and tools that automate the process of integrating code changes into a shared repository, running tests, and deploying the application to production. CI/CD helps maintain code quality and accelerate the delivery pipeline.
