@maskaravivek Sir, My name is Abhishek Garain, BTech 3rd year student from IIIT Gwalior. I am willing to work on this project during GSoC'20. The project mainly revolves around building an UI and an API for contributions calculation which populates the leaderboard. To get a better understanding of building the API, I would like to know about the db schema which is used for wikimedia commons. I have also applied for toolforge tools membership.
