Message

At GetDirected, I architected backend services and REST APIs for a multi-tenant SaaS platform, and developed healthcare interoperability services using FHIR/HL7 APIs. I also optimized key endpoints, reducing latency by approximately 25%.

Previously, I built SaaS and enterprise services at Vertex and Cognizant using Python and Django/FastAPI. My projects include a SMART on FHIR patient timeline and an event-driven workflow platform built with FastAPI and Kafka.
