Regarding GSoC Projects

Hello Devs, I'm Nadeeshan Gimhana and I'm a Computer Science and Engineering undergraduate of University of Moratuwa, Sri Lanka. Since my experience and interest in the fields Android Application Development, C# , REST APIs , JS I would like to contribute *Improve Fedora Android App - Backend *and * ASP.NET <http://ASP.NET> Core web application for /r/Fedora subreddit and Discord.* How should I begin to contribute those projects ? Should I personally contact the relevant mentors for clarifications or can I use mailing lists ? Best Regards, Gimhana
