Experienced Android Developer that delivers UI-rich Android solutions, including embedded, wearable, and SmartHome applications, using an offline-first approach with clean architecture and strong power efficiency. Proficient in background data processing including geolocation and motion sensors, I effectively work through the full application development lifecycle, from idea to the Google Play Store. I successfully find the best solutions for all types of projects using reliable and modern designs.
Created a battery-efficient background service for accelerometer/gyroscope continuous data collection. Actively worked with the REST API and added multiple functional tests.
Developed a complex camera application from scratch, for Horos in Kyiv. Integrated OpenCV into the app to stitch images.
Worked with Microsoft, IoT Lab accelerator in Kyiv. Created a prototype payload device for a high-altitude balloon equipped with wideangle cameras, an onboard GPS, barometer, thermometer, high capacity battery, and solar panel.

Application collects sensors (accelerometer and gyroscope) data and checks if acceleration reached fall threshold. Then application prepares sensor data for the last two seconds (max duration of fall) and sends request to back-end. On the back-end we have Flask Python service with TensorFlow for Machine Learning. Currently we use Deep Neural Network Classifier which gives us accuracy of approximately 80%. So the back-end side can decide in more precise and accurate way if the person actually fell to the ground and needs help. Application gets response and now knows it should notify list of predefined and chosen friends by alarm message containing GPS coordinates and call for help.
