Hi, I am Jubair Hasan, but everyone calls me Joy. Online I go by DarthDemono. I am a second-semester Computer Science BSc student at ELTE in Budapest, originally from Bangladesh.

Outside of university I spend a lot of time on self-hosted infrastructure, systems programming, and the occasional deep dive into networking or cybersecurity. I hold a Fortinet Certified Associate credential and have certifications from Cisco, IBM, and others - around 13 in total.

I also serve as General Secretary at Agamir Hashi, a youth-led NGO in Bangladesh focused on community empowerment.
