- 10+ years of experience including 7 years of java and about 2.5 years of Scala. - High level of Scala and good level of FP (can deal with Free Monads if needed) - Experience in tech leading. - Can start working with almost any scala tech in a short period of time.

Java, Scala, SQL, Spark, Cats, ZIO, Functional programming

- Designed and developed integration testing framework from the scratch with one more team member. - Took over technical leading role from previous lead on project consists of 3 developers. - Played tech lead roles in two more projects. - Switched to pure FP approach. - Good reputation on StackOverflow

- Functional programming libraries like cats, zio, fs2 etc. Or strong willing to move toward FP approach. - There must be complex engineering problems. Not just a lot of small tasks. - Backend only. - Not banking domain. - Not looking for Java + Scala project. Scala only. - Not looking for Java-like Scala project. Strongly oriented on functional programming. Prefer fs2 over Akka Streams and ZIO over rest of IOs, but can work with all of them. - DDD would be nice. - remote work is preferable.
