Experienced software engineer with main focus on efficient data processing using various technologies: SQL, Python, Java, C#, Spark, various ETL and data processing engines (DataBricks, Azure Data Factory, Informatica Power Center, Talend). Primary area of expertise is building data processing pipelines both for Big Data batch processing and live data streaming. I've extensive experience in handling geospatial data using Spark, Python and traditional SQL databases. I also have a lot of interest in optimization for Big Data piplines both in low-level execution plan analysis, but also on design and architecture level.
