BigData Software Engineer (Scala), Kiev 🔥

Kyiv · $3000 · 3 years of experience · Upper Intermediate

Hi, I am a BigData / Scala developer, I performed tasks like Hive, bash migrated to Scala + Spark, worked in the GCP cloud, rewrote SQL on Spark DSL. Migrated Spark + Hive on Airflow + BigQuery + Spark I plan to develop in the direction of Scala + Spark - ideally a project is suitable for me where there is both a back-end and BigData with Scal, Spark VCS: git (GitHub, Gerrit)

Scala, Sbt, Spark, Docker, BigData, Hive, BigQuery, Airflow

Skills in working with functional programming patterns in Scala, modest contribution in ZIO. Structural ETL knowledge with Spark + Scala in BigData. The ability to do WBS. Work with the expected ETA in sprints. Self study skills

I don’t want to work with Python, the maximum is config settings for launching Spark. Ideally, a Spark (Scala) project with a Scala back-end

Привет, я BigData/Scala developer, выполнял такие задачи как Hive, bash мигрировал на Scala+Spark, работали в GCP cloud, переписывали SQL на Spark DSL. Мигрировал Spark+Hive на Airflow+BigQuery+Spark Планирую развитие в сторону Scala+Spark - в идеале мне подойдёт проект где есть как и back-end так и BigData аналитика VCS: git (GitHub, Gerrit)

Scala, Spark, Sbt, Docker, Big Data, Hive, BigQuery, Airflow

Навыки работы с функциональными паттернами программирования на Scala, modest contribution в ZIO. Структурные знание по ETL с Spark+Scala в BigData. Умение делать WBS. Работа с ожидаемым ETA в спринтах. Умение самостоятельного обучения

Не хочу работать с Python, максимум это настройка конфига для запуска Spark. В идеале проект Spark(Scala) со Scala back-end
