Background

About Mahesh Vankayala

I build intelligent, interoperable healthcare systems at scale. As a Principal Software Engineer at Oracle, I build AI-driven platforms and payer interoperability solutions that streamline clinical workflows, reduce friction between payers and providers, and accelerate authorization and reimbursement processes. Over 11+ years, I have owned mission-critical initiatives across Optum (UHG), Ascension, and Oracle—spanning eligibility verification, prior authorization, claims adjudication, prescription fulfillment, and digital member experiences. My work translates complex healthcare regulations into resilient, real-time platforms that improve care delivery. What I'm known for: Healthcare interoperability: Deep expertise in FHIR/HL7 standards, payer APIs, eligibility and benefits verification, prior authorization workflows, digital ID cards, and claims processing. AI agents in healthcare: Designing task-oriented agents for utilization management, coverage determination, and provider communications with focus on safety and auditability. Enterprise platforms: Event-driven microservices architecture, low-latency APIs, and secure data pipelines across OCI, GCP, and AWS with strong PL/SQL and multi-database experience. Security and compliance: Identity federation, data privacy protection, comprehensive auditability, and standards-aligned architectures across regulated healthcare environments. Selected impact: Prior Authorization modernization (Ascension): Streamlined dual-component authorization processes to reduce administrative burden and accelerate decision-making. UHG Eligibility and Referrals (Optum): Built core APIs for coverage determination, cost estimation, digital ID cards, and prior authorization enforcement. OptumRx Fulfillment: Automated compliant home delivery systems with pharmacist review processes, payer integrations, and delivery orchestration. Oracle: Advancing AI-enabled payer and provider integration using Micronaut, event streams, and secure data exchange protocols. Core technical stack: Java, Spring Boot, Micronaut; Kafka, REST/gRPC; PL/SQL; OCI, GCP, AWS; FHIR/HL7, EDI, payer and provider APIs; comprehensive security and SSO/identity federation. I am passionate about elevating healthcare through trustworthy AI and interoperable systems—where measurable outcomes drive success: lower costs, faster authorizations, safer medication management, and enhanced patient experiences.
