Hello. My name is Golovach Ivan. I’m remote Scala/Java contractor with specialization in complex topics on JVM (functional programming, concurrency, distributed systems, crypto). This blog contains some my ideas on there topics.

I come from classical math. As a usally my work is - optimization high performant network servers (game, casino, IoT, …) - and/or refactor some server side code to standarts.

Performance and concurrency come from network and distributed systems.
