Jacek Kmiecik is a Big Data consultant with 14 years of hands-on experience designing and implementing scalable data platforms across on-premise and cloud environments. He specializes in Java and Scala development for Hadoop ecosystems—Spark, HBase, Hive/Impala, Kafka and related tooling—and has led architecture and delivery in digital transformation projects for clients like AirPlus and Nordea. Comfortable bridging engineering and BI, he pairs low-level data engineering with business-facing analytics using Pentaho and PowerBI. His background in research-driven prototyping at Boeing’s Jeppesen and an MSc in Computer Science give him a knack for turning experimental concepts (e.g., social-media-based alerting) into production-ready systems. Based in Frankfurt, he is equally experienced in cluster architecture decisions and day-to-day Spark/Scala coding, making him effective both as a lead engineer and a developer-contributor.
