Senior Software Developer & -Architect

A windows client, consuming a REST API of an embedded-hardware-running server had to be implemented with UI requirements which target a touch-only panel-pc in the industrial domain.

I was in charge of the client architecture and implementation. It defined a cross-project UI-shell that is injected with project-specific views and UI-components. Main features were user management, order management and processing overview.

I compensated missing capacity in the Scrum team and jumped into the project without need of more information than the code and requirements.

I supported the customer in hitting a release deadline. A part of the app consisting of an overview- and detail-page was defined by design templates and a description of the backend APIs. The project was successfully completed with no friction and almost no need of synchronization.

The task was to create a solution in which the user can switch seamlessly from the portrait-mode video-call to a landscape-mode tools section and to create the respective tool-widgets.

In order to fulfill given requirements, I developed coordinate-systems, custom-made sliders, etc. One additional difficulty was to scale the widgets/fonts correctly from small-screen devices like the iPhone SE to tablets like the iPad 12.9”. Furthermore, the tools include a screen where spots had to be placed exactly on top of defined positions of a vector graphic.

The project challenged in managing rotation, controlling a video-call, scaling the layout correctly on multiple form-factors and operating systems and to keep the screen states intact between such orientation changes and switches between edit and read modes within these tools. The resulting solution was of library-quality; almost no dependencies and of clear software-design.
