Summary
👤
Senior🎓
Top SchoolJongwon Choi is a data engineer based in Seoul with a decade of experience building data platforms and dismantling data silos across fast-growing companies, including Kreditdata (acquired 2021), Wantedlab (IPO), and Alarmy. He combines hands-on engineering with short stints in management, most recently serving as an Engineering Manager before returning to a senior data engineering role. Jongwon focuses on core data engineering domains—ETL, data infrastructure, and organizational data maturity—while treating operational bottlenecks as the levers for higher output. He cultivates continuous learning through daily side projects, open-source contributions, and community activity, and maintains a public career archive at jongwony.com. Trained in mathematics and computer science, he brings analytical rigor to system design and a practical bias for reducing organizational friction. An understated strength is his habit of planning around the "limiting step," applying production-grade process thinking to both engineering and team workflows.
