01 — About

About Me

Being in the job industry since 2017, I have navigated through various professional environments — from sales and customer-facing roles to data engineering and software development. My experience in sales has forged me into a strong communicator with a people-first mindset that I carry into every technical role I take on.

I'm passionate about data, machine learning, and the way technology can solve real problems. I love to learn across disciplines — languages, design, and engineering all live on my radar. I studied abroad at the University of Osijek in Croatia through the Erasmus+ programme, completed a Bachelor's in Industrial Design & Production Engineering at the University of West Attica, and wrote an AI-based thesis on Human-Robot Interaction and Trust.

Currently based in Rotterdam, NL and actively learning Dutch. 🇳🇱

Interviewing Myself

What are your hobbies outside of work?

Working out and gaming — so yeah, pretty competitive by nature. But the goal is always to beat my past self, not anyone else. Getting 1% better every day is the real game.

Are you interested in learning new technologies?

Always. I love how technology evolves and becomes more ergonomic over time. Right now I'm deepening my full-stack skills and keeping a close eye on advances in ML and data visualisation — the future genuinely excites me.

What's the technical challenge you're most proud of?

Teaching myself a big chunk of HTML/CSS/JS with no formal front-end background — and then shipping real projects with it. It proved to me that passion has no ceiling.

What do you value most about a team?

Clear communication and smart task allocation. A well-organised team doesn't just deliver — it teaches and learns as it goes. That knowledge-sharing dynamic is incredibly powerful.
