My name is Dmitry Tolpeko, and I work with multi-petabyte and multi-cluster data lake environments in Amazon AWS. My professional interest is in distributed computing using Hive, Spark, Presto, Trino, Flink and Snowflake.

Currently I live in Málaga, Spain. You can reach me at dmtolpeko@gmail.com or @dmtolpeko.
