Hey @TonyWu, great to hear that!
You can get in touch with either @felixmulder or @julienrf, they are the guys running GSoC this year. Paging @fommil too (Sam Halliday) who may be interested in proposing projects to GSoC.
For now, I don't know which project ideas are being considered, but surely one of the nice people I've mentioned before will let you know. Good luck and thanks for getting involved into the Scala community!
