Developer & QA · Lund, Sweden

I'm an Information Systems student at Lund University who builds and tests software. At Axis Communications I stress-tested firmware updates and troubleshot Linux-based systems, and at Lundakarnevalen I co-developed a registration system for ~8000 users in a 40-person team. I work in Java, C#, Python and TypeScript.

Looking for developer and QA roles in Lund and Malmö. Graduating June 2027.
