I study Information Technology and build things I actually use — transport tools, servers, web apps. Economics and accounting help me think about tradeoffs, not just code.

Background
My focus is Information Technology. I also study Economics and Accounting — they give me a way to weigh costs, constraints, and outcomes when I'm building something.
I like working on problems end to end: figure out what's needed, build a first version, then make it reliable enough that people can depend on it.

Where I'm heading
I want to keep building useful systems and get better at doing it in teams and organizations. Right now that means shipping personal projects, competing in CTFs, and learning how real infrastructure holds up over time. I'm looking for environments where technical work has clear impact — not just slides about impact.
