You sound like a great candidate, Upekshe! Either I or Tony (or someone else between us) would be your mentor for this.
My recommendations for your proposal:
* Include a week-by-week rough schedule of what you'll work on over the summer.
* Include a plan for the case where your project will finish early or take longer than the allowed GSoC period.
* Plan to chat with mentors at least a couple times each week and be prepared to treat GSoC as a full-time job.
Looking forward to working with you!
