Reference: to the mail on 25th of March 2016
This is to bring to your notice that I have applied for GSOC 2016 with
Project Title-STRUCTURED OUTPUT for ORG:STRACE, under your Mentorship.
Kindly provide with the technologies to be used and a brief description of
the work to be done.So that I could start working on the Project right away
and showcase you the basic layout and some constructive work for the
Project.With this you will be able to decide whether you would consider
opting me for the Project.
We can have a Skype session if you would feel suitable for an interactive
session.
