Experienced software engineer with few last years spent on creating BigData solutions for different types of businesses, mostly in adtech. I believe and strive to lead my efforts to achieve technical excellence on par with meeting business goals. I do not stop learning new things to match that target and be able to help my teammates. I'm familiar with knowledge domains of adtech, banking and online gambling from variety of my past projects and would be glad to pick up something new for me. I'm passionate about functional programming and opensource, being semi-active contributor already. Ready to introduce and go with variety of devops tools and methodologies be it cloud provider or on-premise enviroment: SRE, USE method, etc. I've went through lots of programming techologies and would consider them in right situation, but I'm better with those: Languages: Scala, Java and JVM-languages in general, C BigData solutuins: all about Apache Spark (batch and Streaming), Apache Kafka, Apache Nifi, lots of other components to create ETL pipelines Frameworks: Akka, Vaadin, Play, ZIO DBs: SQL, ORMs, Hive, Vertica, MemSQL, PostgreSQL OSes: Linux, Solaris and other UNIXes Clouds: mostly AWS (IaaS/PaaS, serverless), bits in Google Cloud and Azure
Spark, Linux, Scala, SQL, CI, Kafka, Vertica, Big Data, data warehouse, AWS, Google Cloud
I've contributed to OSS projects as it's vital to return to community for overall benefit and I'll do it in future. I've already presented my ideas and findings on meetup events in Ukraine.
I'd prefer something other than adtech project, but this is a matter of discussion. I've successfully mentored few junior developers and supervised technical solutions to keep them with BigData best practises, so I'd consider tech lead positions too. If you already have or want to build data engineering team, I'd be glad to help your company with that. I would show up in engineering of BigData project, so both sides - me and your company - could benefit from that.

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.

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.

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.
