Big Data and Back End developer for a team working for Metabiota, a San Francisco-based start-up. As part of the team I worked on developing a solution that helps prevention and monitoring of biological threads. As part of the solution we have implemented multiple services written in Play Framework (both Java and Scala) as well as ETL pipeline that process needed data and stores the results for access by the micro-services. The ETL Flow was implemented using established big data technologies like HBase, Spark, Apache Phoenix and Apache Airflow. I was involved in all stages of development for the mentioned solution: design, implementation, unit testing and functional testing.
