At Telus Digital, I engineered a React Native design system adopted by 10 teams across 10+ apps. I translated Figma designs into accessible, themed components and helped reduce UI bugs across consuming apps.

I also developed a TypeScript chat client for an AI assistant serving clinical research associates and a PDF viewer that cut document verification to under two minutes per 1,000+ pages. I shortened iOS release time from about five hours to about 40 minutes with Azure DevOps and Fastlane.

At Rhaeos, I improved the patient app and built the clinician app for FlowSense, an FDA Breakthrough Device-designated hydrocephalus shunt monitor. Earlier, at Eminent Technology, I delivered web and mobile applications across enterprise engagements, including a telemedicine platform serving 10,000+ users.
