Have some non-commercial experience with Scala/Akka/Spark. I have some experience with Golang and Java. Currently, i work as python/django developer and have more than 3 years of experience. During my work carrier I developed different projects: system for medical recommendations; sports betting platform; cybersports events aggregator; rest api for app like Uber; rest api for dating app; etc.
Create a realtime map with indicators of current meetups in the world. For that project, i use Spark and Spark streaming, for web socket connetions - Akka-http. All data are storing in Cassandra with some processing.
Interesting projects with a professional team without frontends tasks.

Worked with different Scala and Java projects. Low level (platform that communicates via network with small devices, detectors and so on) and high level web apps. With synchronous and reactive behaviours. REST and messaging based commucation. Etc... Latest experience: casino platform with Scala, Lagom, Play, Akka, Kubernetes, Cassandra, Kafka, ElasticSearch, GraphQL.
Full time or part time, preferably remote. Or if office - preferably flexible with possibility to take some day-offs (1+ days non office work). I prefer Scala projects. Would be a plus to have ownership over the code: not only code, but be tester and devops for it. So, having tasks to work with infrastucture also. Woud be be a plus if there is need to work with frontend (React for example). Would be great if you need 2 Scala devs. I have a colleguage with who we want apply to same project.

1) Senior Software Engineer SSP development (https://en.wikipedia.org/wiki/Supply-side_platform). Technologies and tools used: - Scala - Twitter Finagle - Kafka - Lua - Eclipse Memory Analyzer On this position I mostly involved in new features development, finding and optimizing hot spots, performance optimization, incident investigation and stability improvement. Our team is in charge of a couple of microservises, most of them are highload, low-latency and require 24/7 access. I did a great work improving performance of the system, which includes digging into JVM, Linux, Scala libraries, algorithms and data structures, IO interactions etc. I designed and implemented platform for continuous performance testing, which is used in conjunction with CI/CD. 2) Senior Software Engineer at EPAM System Developed data ingestion flow for large retail company. Involved in processing up to 100GB daily data in Spark on Azure cluster. Part of the data was prepared and queried via Hive. Technologies and tools used: Kafka, Spark (Scala), Hive, HDFS, Azure 3) Senior Java Developer at iFuture On this position I : - developed online casino; - integrated two online games providers; - created CMS for manage stuff like games, banners, promo etc; - developed system for managing transactions; - developed system for reports(profit and loss by users, product etc.); The system itself consists from a bunch of microservices, which communicate with each other via REST or Kafka, and a couple of monolitic services. I used docker for local development, Spring Boot freamework as a DI, WEB, AOP framework, Spring Cloud (Feign and Hystrix clients), JPA (HIbernate as an implementation), Postgresql and Oracle as a databases, EHCache for caching, Redis for caching and zero-downtime deployment. Also, I was in charge of: - monitoring the system (NewRelic, Zabbix); - architecture improvement. Here I was mostly focused on following best practices for microservices development: 12-factor principle, config server, request tracing, choreography over orchestration if it makes sence; - performance improvement: caching slow queries and remote calls, resolving slow queries (Hibernate), - codebase improvement: Lombok, monitoring aspects, unit testing
