Project History
Celo Mobile Application
https://www.celohealth.comI developed and maintained an iOS healthcare collaboration application, working closely with the broader team to define its architecture and development processes. We built a robust smart-client application with secure messaging and offline support, ensuring seamless communication and reliability in healthcare settings.
EQUA Smart Water Bottle Application
https://apps.apple.com/nz/app/equa/id1319201641I independently developed an iOS application that connects to a smart bottle to track drinking habits. I designed a seamless user experience, implemented a background Bluetooth connection to the device, synchronized data with a remote server, and integrated HealthKit. To encourage better hydration habits, I incorporated gamification elements and generated intelligent local notifications. I leveraged machine learning to process data and enhance user insights. Additionally, I built a companion application that connects to multiple devices to improve the machine learning model.
GlobalID Mobile Application
GlobalID combines messaging, a financial wallet, and verifiable credentials to provide users with a secure and trusted service. As a mobile architect, I defined the technology stack and implementation strategy. I built a comprehensive product featuring a modern messaging system, a financial wallet, a crypto wallet, verifiable credentials secured by blockchain, and additional capabilities to enhance trust and usability.
