At Zelis, I build a strategic ACH corrective-payments platform that automates payment recovery, eligibility validation, approvals, provider communication, and reconciliation. I develop event-driven C# and ASP.NET Core services with AWS SQS/SNS, Aurora PostgreSQL, Snowflake, REST APIs, and Blazor workflows supporting large-scale incident communications.
I've maintained ASP.NET microservices handling 100,000+ daily transactions, improved data-retrieval performance by 30%, increased test coverage from 65% to 90%, and reduced production defects by 40%. Previously, I delivered backend and asynchronous workflow systems at Zelis, reduced analytics costs by more than $30,000 monthly at Volvo Group, and contributed to Allegiant Air's online flight-booking experience using React, Next.js, and TypeScript.
