About me

My programming journey began in 1995 when I wrote my first lines of Z80 assembly code, alongside my studies in electronics at the Reykjavik Technical College, where computers were a secondary subject. I pursued this interest further, earning a B.Sc. in Computer Science from Reykjavik University in 2001 and an M.Sc. in Computer Science from the University of Skövde in Sweden in 2003. Since then, I have worked as a programmer for various companies, tackling diverse projects involving SAP, Java, JavaScript, C++, and C#, as well as backend services such as SOAP and REST.
