Building things
that ship, not just compile.

I'm Alexander Nicolaou, currently studying Information Technology with a focus on Data Engineering. My goal is to build a career as a Data Engineer or Software Engineer — designing reliable systems and clean, trustworthy data pipelines. Below is a snapshot of what I've built so far and what I'm working on now.

about

I'm an Information Technology student and aspiring Data Engineer, working toward a career as a Data Engineer or Software Engineer. I code in Python, SQL, HTML, CSS, Java and JavaScript, and I'm currently expanding into C++ and C#. I'm always keen to learn, take on new projects, and connect with others in tech and data.

Feel free to check out my work on GitHub, or reach out if you're hiring for internships or entry-level roles in software or data engineering.
