The person behind Walcho

About me

I combine software engineering, product development, and business thinking to build digital solutions that are technically solid and commercially useful.

With a background in Software Engineering and Management from TU Graz, I work across coding, product development, business analysis, and technical decision-making. My experience ranges from open-source Android development and university teaching to business intelligence software, mobile products, and startup projects.

I value clear communication, ownership, structured problem-solving, and a hands-on approach. I am especially interested in projects where software, product strategy, and business value come together.
