Swapnil Gupta is a senior application developer and technical lead with over 19 years of experience designing, developing, and modernizing mission-critical healthcare and financial systems. His expertise spans COBOL, JCL, DB2, Python, Go, Kafka, and AWS, with deep specialization in regulated healthcare domains including ACA, Medicaid, Medicare, and pharmacy benefit management. He has built a reputation for architecting solutions within complex legacy COBOL environments while delivering platform transformations that preserve uninterrupted production stability.
Since December 2019, Swapnil has served as Senior Application Developer/Technical Lead at Pharmacy Data Management Inc. (PDMI), where he diagnosed the failure of a multi-year COBOL modernization effort and architected a hybrid, event-driven integration framework synchronizing COBOL data into MySQL via Apache Kafka, Python, and AWS Lambda. He introduced logging hooks across roughly 120 COBOL programs, built a COBOL-to-MySQL data access layer using Go and C, and engineered a parallel processing framework bringing controlled concurrency to a sequential COBOL/ISAM environment.
Earlier, at HM Health Solutions (2015–2019), Swapnil led ACA processing and regulatory compliance initiatives, owning operations during high-risk annual renewal cycles and leading a Medicaid data migration covering more than 270,000 members. His career also includes leadership roles at Tata Consultancy Services (Citibank, Bank of America) and Wipro Technologies (Mastercard), spanning payment processing, OFAC compliance screening, and card authorization systems.
Swapnil holds a Master of Engineering and a Bachelor of Engineering from India, and is a published researcher with peer-reviewed work in control systems and power electronics presented at IEEE conferences. He mentors engineering teams on modern, production-safe modernization strategies.
