Lakos at the Vujicsics Tihamér Primary Arts Education Institution in Szentendre. At the age of 12, he composed his first piano pieces.

In 2018, he was the only Hungarian finalist in the “Key to the Future” opera writing competition with his first opera. His compositions have been performed at contemporary music festivals abroad, and he has received commissions from Hungarian choirs and musical theaters.
