Thomas got his interest in motorsport and motorised vehicles early on from his father,[1] who constructed a go-kart for him out of scrap iron.

For 50 Swiss Francs they rescued an old Daihatsu Charade from the scrapheap and converted it into a racing car for gravel tracks in many hours of work.

In 2015, he won the Swiss Autocross Championship and became champion in the 3 Nations Cup (Switzerland, Germany and France, after junior wins in 2012 and 2013).

At the age of 20, with autocross success under his belt, Thomas decided to buy a Renault Twingo R1 and compete in the Swiss Junior Rally Championship.

After an intense year with a large fight against Jonathan Michellod, he was able to win the title[4] with three victories, despite one engine failure.

[9][10] He is also part of the Simracing team "NIANCO esports" founded by pro racing driver Nico Müller.

[11] Since 2019, Thomas has been one of the AutoX and Endurance drivers in the AMZ Racing Team, which competes in international Formula Student events.
