Bharath Sundaresan

@bharathsundaresan1

I lead healthcare EDI platforms, Edifecs delivery, and production automation for reliable payer operations.

At CareSource, I lead the end-to-end Edifecs platform buildout, from infrastructure configuration and automated provisioning through validation and go-live readiness.

I bridge business, engineering, QA, infrastructure, vendors, and trading partners to turn healthcare requirements into Edifecs solutions, releases, and durable production improvements.

Across Cigna and Centene, I led healthcare EDI integration, platform upgrades, trading-partner onboarding, production support, and SLA delivery for business-critical payer operations. I also built Centene's enterprise EDI production support organization and led onshore and offshore teams.

I use Ansible, PowerShell, AI-assisted engineering, and self-healing processes to reduce manual intervention, improve reliability, and resolve recurring transaction issues permanently.
