About me
• 1st place in the 12th grade and 2nd place in the 11th grade at the Mathematical Olympiad's county phase. Honorable Mention in the 12th grade at the annual "Traian Lalescu" Mathematical Competition's inter-county phase. • Took part in a teens political party as I want to be part of the people who make the community better. I presented a Basketball Court project to my city's mayor and it was implemented in 2015. It is around 14m long and 7.5m wide, and it's still freely used in the central park of my natal city.
• In my spare time, I like being creative and working on personal projects, both IT and non IT related, so I made a Stereo Speaker of ~120cm length and ~50cm height from scratch, and it has been staying connected to my TV using Bluetooth for years now.
