I'm happy where I am right now, but everything is possible for the right price.
In the past I worked on projects in different domains using different technologies including java, node.js, php, python, so picking up a new language won't be a problem.
In the future I want the main focus to stay with functional paradigm: scala, rust, closure, etc. Switching to managing positions is also an open option for me.

Recently I was a Scala engineer on a project which was a part of huge pipeline of data for generating HD maps for autonomous driving. The project was built on flink. My task was to support the service: improve the code, fix bugs, deploy and undeploy using Gitlab CI and kubernetes, monitor with Grafana and Splunk (and introduce new metrics), measure performance.
I'm good at explorative tasks and at spotting (and solving) problems. I like optimization, refactoring, DevOps tasks like CI/CD, automation, monitoring and improving docs.
I'd like to learn how to design scalable distributed systems. I'm also looking to gain some experience with functional effects (ZIO, cats-effects or monix). In spring I started a frontend web development course to be able to implement my ideas. I'm also interested in noSQL DBs. I would like to acquire skills that would allow me to become a team lead.
I migrated a suite of separate sbt projects to a multi-build configuration.
I also did a presentation in ScalaUA conference on akka-http which I'm not really proud of :)
On my penultimate project I did some performance research, improved performance and quality of results.
On my last project I restructured and improved documentation, fixed and improved dashboards, made configuration more structured and typesafe, deleted some code and re-wrote a lot of it in a more concise and Scala manner and made it more efficient. I also found a cause of mysterious continuous service restarts which helped create a solution for them. I became one of the key engineers in the team.
Basically whatever problem I had in front of me, I figured out a solution.
