Summary

Senior🎓
Top SchoolSangrho Lee is an Executive Director and seasoned data engineer with nine years of experience designing and operating large-scale data platforms across finance, payments, and media in Seoul. He combines strategic leadership—overseeing market analysis, budgeting, campaigns, and recruitment—with deep hands-on expertise building secure, audited data ecosystems using AWS, Hadoop/CDP, Kafka, Flink, Trino, and Iceberg. Notably, he has led AML and credit scoring platforms, implemented enterprise-grade security (ISMS-P, Kerberos, LDAP, fine-grained IAM), and modified open-source tools to meet strict audit requirements. Sangrho excels at bridging product and infrastructure: creating serving layers, monitoring stacks (Datadog/CloudWatch, Prometheus/Grafana), and data lineage with Apache Atlas to make complex pipelines reliable and compliant. He is pragmatic, technically curious (early adopter of Iceberg for upsert limitations), and skilled at turning regulatory constraints into robust engineering solutions.
