Thank you for the vote of confidence, but I'm a decent developer, not a $300k salary developer.
I don't see how that is possible, ignoring the fact that doing that would be about as fun as gold farming on WoW circa 2007.
You'd have to interview about 12 hours a week (including Christmas and Thanksgiving), every week at only SV type companies and only for $300K jobs and pull it off for a year without getting caught before you hit $100K.
Highly unlikely.
