Lead iOS Engineer
2022 - 2022
Swift Medical Inc.
- Led the development and launch of a Bluetooth-connected medical device called Ray1, which provides thermal data to analyze and proactively identify injuries under the skin.
- Built the framework, analysis algorithms, and user interface to analyze the thermal images. The user interface allowed the user to annotate and extract specific data points for further analysis.
- Created the central Bluetooth Low Energy (BLE) service class to connect and manage multiple Bluetooth devices simultaneously. The service optimized iPhones' battery consumption and ensured we managed the resources efficiently.
- Revamped the existing app's architecture to apply a more modular approach to UI components. Made services more independent and modular. Introduced dependency injection and MVVM to existing monolith components.
