Senior Software Engineer, BigData, Scala 

EU, Asia · $6000 · 9 years of experience · Upper Intermediate

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.

My previous job: I was a member of data engineering team that designed Big Data tools and infrastructure for the project that included collecting, processing and analyzing large amounts of (un)structured data mostly from web APIs and different data storages which were in most cases associated with visitor behavior, clickstreaming, marketing, etc. The main idea was to build a platform that provides a data set of all needed online data for businesses and use that data for APIs to improve product recommendations, conversion rate, ads, etc. Responsibilities: 1. Implementing and designing data pipelines. 2. Scala back-end development of microservices. 3. Monitor performance of the project and integrate big data tools. 4. Doing code review, work with other teams including DevOps team, thus improved my skills in this area too.

Before my previous job I took internship at a company, where I was studying Data Engineering, Scala, akka and other tools and concepts for building highload and distributed systems. Also participated in the final project there, which was basically an analyzer to estimate impact of news on cryptocurrency prices for given time frame in the future with given prediction frequency. As a result, it was a system that monitored sources and evaluated the importance and impact of the news. Based on this it predicted the consequences in short and long time interval. My responsibilities were: 1. Giving and collecting data for data scientists from various resources like cryptopanic.com, twitter.com, reddit.com. 2. Building a REST API on Scala. Also. I made some personal projects, like: 1. Admin panel for monitoring orders from hardware stores. It was a university course project which was basically a web-app for monitoring orders from various stores, finding stores nearest to the customers, collecting basic info from employees, store owners, orders' status etc. Designed microservices architecture of the app, implemented backend and frontend, build containerized network of created modules. 2. Project for building a system for cafe without queues. The idea was to build a system for a cafe without cashier attracts queue. My part of the job was to develop a backend part of the system. Moreover, I have certificates from my internship and also from some online courses. like Coursera.
