Senior🎓
Top SchoolDuane Robertson is a seasoned software engineer with over two decades of experience specializing in healthcare claims processing, electronic data interchange (EDI) and X12 standards (997, 999, 277U/CA, 837). He spent a long tenure at Optum ensuring SLA-driven claim reporting, designing parsers and formatters, and automating production processes with Oracle SQL and PL/SQL. Familiar with legacy and enterprise systems—from HP300/900 series hardware and COBOL-era environments to modern SQL-based pipelines—he combines deep domain knowledge with operational reliability. A conscientious, self-motivated leader, Duane established programming standards and on-call practices that kept high-volume claim flows resilient. In retirement he remains technically engaged as an open-source back-end contributor to a notable voxel game platform, showing an unexpected interest and competence in procedural content generation and user-focused features. Based in Colorado Springs, he is currently finishing a bachelor’s focus in cyber/computer forensics, underscoring ongoing commitment to technical growth.
