Hello, I'm Robert Cole

I'm a Software Engineer with a strong background in full-stack development, building scalable, high-quality applications across industries including financial services, healthcare, and cloud-native systems.

Currently contracting through On-Demand Group at Medica, I lead greenfield engineering initiatives supporting internal platforms and infrastructure (including an API observability tool and a real-time Kafka-based data streaming pipeline). Previously at Optum / United Health Group, I specialized in healthcare integrations using FHIR, HL7, and Angular.

I'm currently pursuing a Master's in Computer Science with a specialization in Artificial Intelligence at Georgia Tech while working full-time. This academic work deepens my expertise in areas like distributed systems, intelligent infrastructure, and applied machine learning.
