Top SchoolStefanos Kalogerakis is a software engineer and research associate with eight years of experience building scalable stream-processing and data analytics systems, currently serving mandatory military service in Greece. He contributed to STREAMSTORE at ICS-FORTH, modifying Apache Flink and HDFS source code and designing large-scale ETL pipelines with Flink, Spark, and Kafka to improve elasticity and rapid recovery of stateful stream processing. His industry experience includes developing high-performance query engine operators in C++ at Huawei R&D and building cloud-native ETL solutions on Kubernetes, Airflow, S3 and MongoDB during Big Data internships. Stefanos combines strong academic performance—a top-ranked M.Sc. in Computer Science from the University of Crete and an M.Eng. in Electrical & Computer Engineering—with hands-on systems work, from bash automation to cluster experimentation. He enjoys joining dynamic, innovation-focused teams and has a proven track record of translating research ideas into practical, production-oriented modifications of open-source platforms. Notably, he has experience trading writes for reads in sort/join algorithms to improve throughput under memory constraints—an approach that informed several of his performance-oriented contributions.
