Hi, I'm Rene Senior Software Engineer · Front‑end

I turn business pain points into solutions with technology.

I started in front-end and now think about the whole system: architecture, integration, quality and observability, with AI in my workflow. For over 8 years I've built internal systems for the operations of large companies, always starting from the people who use them.

Manifesto

Technology isn't the end, but the means to turn pain points into smart solutions.

I started as an apprentice and worked in administration and inventory before writing my first line of code. That road taught me to look at the people first — and only then at the tool.

I've tutored students, run technical interviews and enjoy supporting newcomers on the team. Sharing what I know is how I keep learning.

Outside work, my favorite time is with my family. I also enjoy learning about electrical work and electronics, car detailing and a good movie. Deep down, it's the same curiosity about how things work and the same care for details.
