Digital Asset

Jarek Ratajski
I love programming since my first line of code I did on the C64 in Basic. Somewhere in 90ties I've switched from C++ to java and spent then 20 Years developing mostly Java software working for various companies and projects. 
I work at Digital Asset writing Haskell and Scala – but my heart is still close to Java and Kotlin.
