"GSinishtaj" on Full Tilt is Gjergj (George) Sinishtaj, a young American professional poker player born and raised in Sterling Heights Michigan USA, near the Canadian border.
Despite his age, Gjergj has been playing the digital circuit for quite some time; in fact, he started to play for real money at the tender age of 12! Beginning his poker career using his brother-in-law's sports betting account, by the age of 14 Gjergj had built his bankroll to over $100K.
At the time, his username was "P0K3RPR0D1GY" and during his middle school lunch breaks, Gjergj wasn’t playing Magic the Gathering or chasing girls, he was on his laptop, stacking full-blown adults for thousands.
In 2009, 16-year old Gjergj played a series of heads-up matches on Absolute Poker as "BLEWJOB" against Jason Rosenkrantz on the Nationally televised show "2 Months $2 Million", where the 16-year old came out as a $120K winner.
Already at 16 years old, Gjergj had graduated demonstratively to Elite status. Earlier that year he also started a Rakeback company.
When Gjergj turned 18 he was finally able to create an account of his own: "GSinishtaj". He uses the same screen name on all Poker Rooms as well.
