Professional Experience

Centene Corporation April 2024 – Present

Integration Engineer Missouri, USA

• Designed and built healthcare data exchange interfaces (HL7 v2.x, FHIR, EDI 834/837/835) connecting internal systems with 15+ external payer and provider partners using Mirth Connect and Rhapsody.

• Developed REST/SOAP integration services in Java and Spring Boot to support enrollment, claims, and eligibility data exchange between internal platforms and partner systems.

• Reduced interface failures by 30% over two quarters by re-engineering error handling and retry logic across enrollment and eligibility integration channels.

• Built Kafka-based event-driven pipelines to stream real-time claims and eligibility updates, improving mes- sage processing throughput by 40%.

• Deployed and maintained integration services on AWS (Lambda, S3, SQS), enabling scalable, cloud-hosted interface processing with reduced infrastructure overhead.

• Configured and supported Epic interface connections, ensuring accurate, HIPAA-compliant data flow between EHR systems and downstream applications.

• Wrote SQL queries against Oracle/SQL Server to validate backend data mapping and transformation accuracy between source and target systems.

• Maintained interface specification and integration design documentation each release to keep pace with changing partner requirements.

• Sat in daily stand-ups and sprint ceremonies with architects, BAs, and DevOps, keeping integration delivery aligned with a 2-week release cadence.

• Supported production deployment and go-live cutover activities, monitoring interface health and resolving in- tegration issues before they impacted downstream partners. Capgemini November 2021 – July 2023

Integration Engineer India

• Built and maintained integration components for healthcare claims and member data systems on projects serving both national and international clients.

• Developed 200+ integration touchpoints across two major releases, building REST/SOAP services in Java/Spring Boot linking client systems to internal healthcare platforms.

• Configured Mirth Connect channels and Rhapsody routes to process HL7 and EDI transaction files, reduc- ing downstream mapping errors through upfront validation logic.

• Delivered SIT/UAT-ready integration builds for 3+ client rollouts, coordinating cutover activities and documenting interface behavior for sign-off.

• Worked daily with onshore (US/international) and offshore teams across time zones to design, build, and trou- bleshoot integration solutions and keep client milestones on track.

• Put together integration design standards and onboarding documentation that new engineers used to ramp up on interface development within their first two weeks.

• Coordinated with business analysts and architects to translate client interface requirements into detailed tech- nical designs.

• Participated in release readiness reviews, signing off on integration builds before go-live for client deployments. Accenture September 2019 – October 2021

API Engineer India

• Built API-based healthcare integration solutions in Java for national and international clients, covering both functional and system integration scenarios.

• Developed and maintained 100+ REST API endpoints per project cycle, handling request/response payloads, authentication, and error handling.

• Designed integration logic for authentication, data validation, and performance-critical scenarios, reducing downstream integration escapes.

• Authored API specifications and integration design documents used as the reference standard across the project team, cutting onboarding time for new engineers.

• Took part in sprint planning, stand-ups, and retrospectives, keeping integration development in sync with a fast-moving delivery timeline.

• Worked with QA and support teams to reproduce and resolve integration defects quickly, reducing back-and- forth during sprint cycles.

• Helped build out the initial API integration framework used across subsequent project phases. Education
