I am programmer with about 10 years of experience. Big fan of Akka solutions from Lightbend. Constantly trying to know and understand DDD better. I am convinced that more demanding challenge is to design satisfied solution than implementing it. I think that skillful extracting and maintaining valuable abstractions are key to create good system. On the other hand every abstraction leaks eventually, so I like to get know lower-level principles. I believe in value of monitoring and constantly infrastructure development.
