Medical app for diabetes treatment.

Nov `23 - Nov `24

1 year

NDA

This project involved the development of an advanced iOS application ( according to IEC 62304:2006 Medical Device Software standard ) designed to manage insulin delivery for diabetic patients using a hybrid closed-loop system. By leveraging sensor glucose readings, the app intelligently and automatically adjusts insulin doses delivered via an insulin pump to optimize glucose control. Specifically, I developed SDK’s for Freestyle Libre 3 and Dexcom G6 sensors. The application utilizes CoreNFC and Core BLE for seamless communication with glucose sensors and insulin pumps. This combination ensures real-time data acquisition and control, enhancing patient safety and improving diabetes management outcomes. To ensure the security of data transmission and protect patient information, the app incorporates OpenSSL, providing robust encryption for all communications within the peripheral devices. iXGuard was used to obfuscate the code and add additional runtime protection for the app binary.

Responsibilities & achievements

We created IOS version from scratch, while Android already existed. I developed all features of the app

AirAlert App

Feb `22 - Present

3 years

Stfalcon

The app instantly informs about the beginning and end of a civil defence alert in the region. No registration is needed: the user is only required to select the region. Air Alert does not collect users’ or geolocation data. The app generates a loud alert warning of an airstrike, chemical attack, technological catastrophe or other types of civil defence alerts. Air Alert is the only application supporting critical alerts among similar ones. It means that notifications are delivered even in the smartphone’s silent or sleep mode.

Responsibilities & achievements

Developing core functionality, significantly push notification in sleep mode.
