Paweł Dolega
CTO at VirtusLab
CTO @ VirtusLab
Software engineer / manager / entrepreneur. Worked in international corporations and small local software houses (two of which I co-founded). These days my weapon of choice is mostly Lightbend stack (Scala / Akka / Play / Spark) though I am trying to remain flexible and not be too orthodox.
Far more important than actual technology — I am really passionate about technological challenges and problems that technology is trying to solve. I like to work on things that matter.
Last but not least, infrequent conference speaker.
