Summary
👤
Senior🎓
Top SchoolEugene Chung is a seasoned software engineer with 11 years of experience building high-performance back-end systems, databases, and data platforms across companies like Dable and NAVER. He specializes in SQL/big-data ecosystems (Hive, Tez, Trino), ETL pipelines (Airflow, Trino, Spark) and low-level performance tuning—having contributed upstream patches to Apache Hive, Tez, and EOSIO. His earlier career spans RDBMS internals, Java EE web container work, and blockchain/C++ smart-contract development, reflecting deep systems and concurrent programming expertise. At Dable he focuses on Trino- and Airflow-based data pipelines while at NAVER he improved ORC bucket pruning and scheduler/thread-pool behavior for large-scale SQL execution. An active open-source contributor, he blends production-grade engineering with pragmatic improvements (e.g., reducing unnecessary global calls in EOSIO) that make systems measurably more maintainable and efficient. Based in Gyeonggi, South Korea, he pairs systems-level rigor with a track record of performance-driven contributions across both proprietary and notable open-source projects.
