His form since has been a little more inconsistent, but Stamper's confidence has been boosted by victories at the
German and Spanish Opens
in recent months and he heads to this year's World Championship in Puebla, Mexico targeting further success.
"I know if I fight my best I can top the podium and that's my aim," the 2008 European silver medallist told BBC Sport.
"I would love to be the first British male world taekwondo champion and it would avenge a little bit of disappointment from 2012.
"I wish the Olympics were now because I am feeling like my performances have stepped up another level."
Stamper wins -68kg 2011 World bronze
Manchester was recently announced as the host city for the
first Taekwondo World Grand Prix Series event
in December of this year and competitions like these and the World Championships will be key to future Olympic qualification.
"With the new ranking system, the Grand Prix will be massive and really important to put your results down because you could automatically qualify [for Rio] if you are in the top eight," said Stamper, who plans to move into coaching after retiring.
"If my results keep going the same way I will hopefully be at Rio 2016 and go further than I did in London and win a medal, which would be a nice way to sign off."
