As a Sr. Mobile Developer at ONEai Health, I played a key role in the development of both the iOS and Android versions of the ONEai Health app. I was responsible for building the app from scratch, integrating the Bluetooth-enabled device to collect and display vital health metrics such as heart rate, SPo2, steps, calories, HRV, stress levels, and sleep data. My contributions included implementing seamless device connectivity, ensuring accurate data synchronization, and presenting complex health information in intuitive, visually appealing graphs. I leveraged my expertise in Swift, Kotlin, and mobile app development to create a robust and user-friendly experience across both platforms. Additionally, I focused on optimizing the app's performance and ensuring it provided real-time, reliable health data tracking. I collaborated with cross-functional teams to design and implement the app’s backend systems, ensuring smooth data flow from the Bluetooth device to the app. I was also involved

I developed the PDF Scanner App from scratch, focusing on providing a comprehensive and easy-to-use document scanning experience. The app allows users to scan documents quickly with automatic edge detection, ensuring precise and clean scans every time. I implemented features such as the ability to scan multiple pages and compile them into a single PDF, providing flexibility for users who need to scan long documents. The app includes advanced image processing algorithms for automatic enhancements, such as adjusting brightness, contrast, and sharpness, ensuring high-quality output even in low-light conditions. In addition to scanning, I integrated various tools for document management, such as the ability to organize scans into folders and rename files for easy identification. The app supports exporting scans in multiple formats, including PDF and JPEG, with options for sharing directly through email, cloud storage, or other apps. I also added a built-in OCR (Optical Character Recogniti
