Salonlab Smart Analyzer
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. The focus was on quickly adapting the existing architecture and infrastructure to implement new features, reviewing merge requests and to optimize the application.
Spot9
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.
Coca Cola Salesforce
Stability and performance updates for a legacy application. The focus was on the analysis of logs and crash reports in order to make the app compatible and stable with the latest iOS version again. Intense use of a variety of profiling instruments for finding memory and thread related bugs.
Porsche Roads
Development of several new features for a road based recommendation app. Focus was on the implementation of a map, that uses clustering for displaying huge amounts of data and the integration of community features within the user profile.
Mercedes AMG AR
Lead development of two augmented reality applications that use ARKit 2 for the 3d object detection of an exhibit. The first app is a white-label solution for scanning physical objects and for managing / exporting / testing the finished scans. The second, branded, application is able to import these scans and to detect a physical object based on a scan in order visualize corresponding 3d models using augmented reality. The challenges have been the realistic rendering of the AMG motor, as well as stabilizing the user experience by reducing the glitches of ARKit throughout a session.
Mercedes me media
Lead development of a new Daimler AG iOS application that offers first hand access to company specific news and media files as well as a personalized access to product presentations and drive events. The challenge of the long term project was to create an application, that conforms to the compliance guidelines of the company in terms of legal and security issues as well as serving as the technical lead for the mobile team.
The architecture was based on a functional reactive redux implementation in MVVM structure that used a declarative routing engine for navigation and deep links. Obfuscation and encryption was used to protect the app against malicious use. The agile workflow was based on Scrum using Jira and Git Flow. The definition of done contained automated tests, code reviews with pull requests and quality assurance.
