The Salonlab Smart Analyzer is the first device, that allows hairdressers to scan the hair structure of their clients through near infrared technology. The device communicates via Bluetooth with an iPad app, that visualizes the scan process and result. My task was to support the iOS team to finish the application in time.

Tätigkeitsbeschreibung

Lead development of the architecture and CI infrastructure for a large scale banking application. The goal was to build the foundation for an upcoming banking application, that offers traditional banking features, such like managing accounts or executing transactions and also serves as a wallet for digital currencies.
The architecture can be described as MVVMIP (Model-View-ViewModel-Interactor- Presenter) that uses functional reactive concepts, a declarative router for the presentation of view controllers and a Redux implementation for managing the application state. The application also uses advanced encryption for obfuscating credentials or storing user related data. My responsibility was also to setup the continuous integration and delivery process, as well as the documentation of all parts of the project.
