Hello, I'm Alexander.

Status

Proudly working

Hello, I'm Alexander.

I'm a software and data professional who enjoys both the technical side of building systems and the human side of understanding why they matter.

I started in software development and, over time, moved into data engineering, where I found a space that fits me well: improving processes, working with data at scale, and turning complex tasks into clear and reliable solutions.

Outside of work, photography has become one of my favorite ways to slow down and pay attention. I also spend time around gaming communities and personal projects, which has taught me a lot about systems, people, and long-term building.

Curiosity

Always learning through practice.

Leadership

Growing through ownership and collaboration.

Photography
Photography is a personal side of this site. I enjoy portraits, street photography, and urban scenes, especially the small moments, light, and atmosphere that often go unnoticed. For me, it is both a creative outlet and a way to pay closer attention to the world around me.
