Welcome avantika04 , KrishnaCosmic (IRC) and Mohamed Khaled !
For starters, if you haven't already, please read these two pages carefully as they will contain a lot of answers:
https://wiki.musicbrainz.org/Development/Summer_of_Code/Getting_started

and https://wiki.musicbrainz.org/Development/Summer_of_Code/2025/ListenBrainz

For example, there is a link to "easy first bugs" tickets in the second page.
