Healthcare Platform Infrastructure & Development Workflow
About This Project
Built comprehensive infrastructure and development workflows for Millie Health Inc., a healthcare technology platform. Established Docker-based infrastructure, created local/staging/production deployment workflows enabling GitHub flow development, implemented code review processes, and set up AWS infrastructure including RDS and EC2. Integrated MQTT messaging, Twilio communications, and Contentful CMS into a React Native mobile application.
Key Achievements
