BILL AP & AR Business Payments App

https://play.google.com/store/apps/details?id=com.bdc.bill&hl=en_US&gl=US&pli=1
BILL AP & AR is a brand-new app that helps small and medium-sized businesses manage their finances. I was part of the team that developed the app's initial concepts and implemented several key features, including an expandable PDF viewer, swiping to approve or deny a bill, and the bill payment flow.

FreeStyle LibreLink and FreeStyle Libre 2

A mobile medical device app that interfaces with continuous blood glucose monitors over near-field communication (NFC) and Bluetooth Low Energy (BLE) technology. I localized the app, delivering translations for each relevant market. In addition, I implemented market-dependent feature configurations and accounted for performance and patient safety.

Digital Sound Boy App

https://github.com/draglabs/dSoundBoy-Android-V2
The Digital Sound Boy is an Android app I implemented from scratch. It lets multiple users on separate devices record into one session simultaneously. The recorded audio is associated with a jam identifier and then uploaded to an Amazon S3 bucket, which would then be associated with a jam and processed by the back end.
