REST -> gRPC migration for Scala microservices in my current company which led to ~30% network traffic reduction and ~20% CPU reduction
Introduced Apache Kafka to decouple strongly coupled parts of the system. Migrated some of critical ETLs to Kafka to achieve (1) near real-time processing and (2) better processing guarantees
Decomposing a huge PHP monolithic application into smaller microservices. Major improvements to hot-path API endpoints in both p99 latency and resource consumption
Top-8 Apache Kafka answerer of all time on Stack Overflow (was top-2 but haven't answered new questions for several years now)
10 years in software engineering, mostly Scala but also did some Golang 4-5 years ago (open-source). I'm definitely rusty in Golang but could jump back in pretty quickly.

A responsible self-sufficient engineer that can work with minimal guidance, but can also easily work in a team.

Primary technologies - Scala, gRPC, AWS stack, Kafka, k8s, Docker. 

Upper-intermediate English (read\write\speak). Standard stuff like IntelliJ, Git, Jira.
A remote part-time job in either Scala or Golang. Interested in developing high-load systems, but not interested in cryptocurrency startups or anything related to gambling.
I am currently employed full-time and not looking to leave my current job! But my current load allows me to easily take an extra 4h of work every day without any harm. Can start pretty much immediately
