Scala Developer

Kyiv · $4500 · 10 years of experience · Upper Intermediate

For the last 5 years I am working with Scala web projects. Main library at use is Akka (actor, cluster, streams). Database is distributed embedded key-value storage on basis of akka-cluster.

Scala, Akka, NoSQL

My biggest achievement is gradual migration of project which had required a dozen of senior developers to simpler solution which now can be maintained by couple of middle ones. All changes were done on production systems and clients have very positive feedback about changes. Bugs and performance issues have become a rarity. Along the way the product expanded its functionality and introducing of new features takes of magnitude less time now.

Ability to work at home from time to time. Challenging tasks. Good coffee.
