Hobbies
My primary passion lies in sports, with rugby and cricket being my main pursuits since childhood. In 2018/2019, I embarked on a fourteen-month journey around the globe to play rugby. It all began with a trial contract in Perth, Australia. Subsequently, finished playing in The Hague, Netherlands before returning to the UK. Presently, I have returned to play local rugby, actively participating with Letchworth RFC as well as representing Hertfordshire winning the county championships at Twickenham in 2025.
