About

I’m a back-end software developer based in St. John’s, working on telehealth and app platforms where reliability, scalability, and clean API design matter. I build and optimize production systems using Node.js, TypeScript, and serverless architecture, and I enjoy turning requirements into well-structured services that are easy to maintain.

I also bring strong AWS experience across Cognito, API Gateway, Lambda, EC2, S3, and event-driven workflows using SNS, SQS, and Step Functions. From designing RESTful APIs aligned with HL7 FHIR R4 standards to collaborating with cross-functional teams in Agile environments, I focus on shipping secure, testable features and improving performance end-to-end.
