High-school student in Bucharest. I build small things, compete in ML olympiads, and ship the occasional app.

About me
I'm a 17-year-old student in Bucharest, in 11th grade at Colegiul Național "Ion Creangă". Most of my time goes into ML and software, mostly Java and Python through Oracle and Python Institute certifications, and lately Generative AI on Oracle Cloud Infrastructure.
The rest of my time splits between the school's robotics club, volunteer work with Salvați Copiii and a few other organizations, freelance video editing for private clients, and, until 2022, semi-pro basketball with a U16 team in the Bucharest league. Code teaches you to think structurally; basketball teaches you to lose well. Both have been useful.

Private clients
Editing personal-project videos for private clients on a per-project basis. Working with non-technical clients taught me as much about scoping and deadlines as it did about Premiere.
