How to Work With EngineerBabu on AI Agent Development

Your product stage defines your engagement model. We offer three ways to access our AI agent development services, from a single sprint to full end-to-end ownership.

Chief Digital Officer (Hospital / Health System)

Your current patient portal has a 28% adoption rate-patients complain it's hard to use, slow to load lab results, and doesn't work on mobile. You need a modern, mobile-first portal that integrates with your existing Epic environment via FHIR R4 and drives digital patient engagement scores required for MIPS and value-based care contracts.

Building a HIPAA-secure, ONC-compliant digital interface giving patients access to their health data-lab results, medications, visit summaries, care plans-via FHIR R4 EHR integration, plus appointment scheduling, secure provider messaging, prescription refills, bill pay, and health record download.
