Who Am I

From the court
to the code

I'm a 22-year-old of Romanian origin, raised in Spain. From a young age I was immersed in competitive sports — Taekwondo and Basketball were my main focus, where I built an unbreakable character and an intense drive that pushed me to become a high-level athlete in my local community.

At 18, I made the deliberate decision to step away from competitive sports and direct that same hunger toward education and business. I've always had an entrepreneurial streak — building small ventures since I was very young — and now I'm channelling all of that energy into Tech and Business.

I'm studying at the Universidad de Málaga, specialising in Marketing & Market Research, with a growing focus on data analysis, Python, AI and financial modelling.
