What I'm looking for

I'm available for senior software engineer roles.

At Orion Innovation, I led the technical architecture for a real-time healthcare system that processes customer-agent conversations on AWS. I engineered live transcription and sentiment analysis, with automated responses and contextual information retrieval through Amazon Bedrock.

At MedMatch, I joined as a founding engineer and advanced to Chief Software Architect, shaping a healthcare matching platform with EHR integration and serverless AWS infrastructure. Earlier, I built event-driven retail systems at foryouandyourcustomers and microservices at BrightMarbles, including a domain provisioning workflow using the Saga pattern.
