Who I Am

I'm currently pursuing my IT degree at inHolland University of Applied Sciences in Haarlem, Netherlands. I focus on building software that solves real problems — whether that's a banking system, a ticket management platform, or a trading tool.

I'm passionate about data processing and backend engineering — designing clean database schemas, building reliable APIs, and understanding how data flows through complex systems. Outside of school projects, I explore algorithmic trading and crypto tools.

Away from the keyboard, I've been into music production and DJ'ing at venues since my teenage years — a creative place that keeps me sharp on the details.
