This is a simple datalake - CRUD - used to store photos. It's used by other small project(s) as part of a machine learning playground that downloads photos from a 3rd party source, stores them here and then builds dataset for computer vision tasks. The structure of the project is microservices-like so this is just one part.
The project uses a simple REST framework (Javalin) and simple SQLite framework (Exposed) for faster iteration and improvements.
The rest of the projects would be listed here with very short descriptions.
