About

I have done two internships: Android development in Kotlin at Skiller Academy, then cloud consultancy at Axazure, writing C# for Dynamics 365 and automating Azure workloads. The second one is the one that stuck. I would rather work on what a product runs on than on the product itself, which is also how Linux ended up as my daily driver. In September 2026 I moved to Denmark, where I am now studying Computer Science at SDU, and I am looking for work alongside the degree, part-time or as an intern.
