Jaswanth Koorapati

I’m a Mainframe Data Engineer with 4+ years of experience in healthcare and insurance claims systems. I focus on high-volume batch and online transaction processing, translating business needs into compliant data solutions.

In my recent roles, I developed and enhanced COBOL programs for insurance claims adjudication, processing 1M+ records per month with 99.9% accuracy. I designed and optimized JCL batch job streams, cutting nightly batch processing time by 35%, and improved DB2 eligibility/benefits lookup performance by 40% by embedding SQL in COBOL. I also automated error handling and restart/recovery with Abend-AID, reducing manual intervention by 50% and supported SIT/UAT by resolving 100+ defects.

I bring that same delivery mindset to my projects, from a COVID-19 Claims and Vaccination Tracking System—processing 2M+ records monthly—to a Medicare Secondary Payer Reclamation System that improved payer coordination accuracy by 45% while ensuring compliance with CMS guidelines. I value collaboration with QA and business stakeholders and I’m committed to data quality, reliability, and HIPAA-aligned execution.
