A complex app for a big embedded hardware development company Utilizing my expertise in Kotlin, Room, Retrofit2, Okhttp, and MPAndroidChart, I almost single-handedly developed and implemented a user-friendly app that was able to authorize users, connect to circuit board via Bluetooth Low Energy, and display circuit output in various forms. One of the key challenges I faced during this project was the lack of API documentation, which required me to intercept requests from the company's site to the new and legacy back-ends to gain access to the necessary behaviour information.
