Top SchoolOwen Gallagher is a data engineer with a decade of hands-on experience building and refining data systems, most recently leading merchant-services data engineering at JPMorgan Chase. He combines backend payments expertise with practical automation—streamlining data transformation, querying, and reporting workflows for large-scale finance environments. His background spans system-level engineering for automated trading, cross-platform desktop applications, and research-focused VR projects, reflecting both breadth and a knack for translating domain-specific problems into robust software.
