My name is Szymon Halastra. For last 7 years I have been developing mobile and web applications. Most of the time I have been working with Java, but I am heavily interested in JVM languages, such as Kotlin or Scala. Since some time I am also diving into Data Engineering topic.

Except technological things, my interests cover urban design, urban planning and sustainable transportation.

Goal of this blog you are currently reading is to merge urban world with data engineering and programming per se.
