Mariusz S.
Data Engineer
I have over 9 years of experience in Data Engineering (especially using Spark and pySpark to gain value from massive amounts of data). I worked with analysts and data scientists by conducting workshops on working in Hadoop/Spark and resolving their issues with big data ecosystem. I also have experience on Hadoop maintenance and building ETL, especially between Hadoop and Kafka. You can find my profile on stackoverflow (link in Portfolio section) - I help mostly in spark and pyspark tagged questions.
