I am a senior .NET developer with more than nine years of experience in .NET and web development. I am used to agile software development methods and to work independently. I like to teach junior developers and leading teams by example. Because of my broad knowledge in various technologies I am often the one who develops proof of concept applications for our customers. In my spare time, I am exploring new technologies, work on GitHub projects and take pictures.

Project History
Maritime solutions
- I'm responsible for the architecture, design and development of an application ecosystem for the maritime industry.
- Management of the different development teams.
Maritime app collection
- Internal and external customer requirement analysis.
- I was responsible for the architecture, design and development of single purpose apps for the maritime industry.
- Management of 2 remote development teams as product owner and trainer.
- I was responsible for the design and the transition of the internal IT towards the cloud.
Mobile Websites
- I was building a survey app for a company in the offshore industry to get immediate customer feedback of the food quality and cleaning services.
- My solution was to build a customizable website what could be used for different questions and run on any device.
- To minimize the traffic, I build all logic in JavaScript and only send the customer feedback to an SQL Server in the Azure cloud.
CRM Bulk Edit POC
- We build a proof of concept console application that can export CRM records into an excel file and could also import the extracted excel file back to CRM. The data that should be exported could be specified by customizing the configuration file. The customer demand was that a user wants to export some CRM data into an excel file to use the Excel tools to be faster in editing multiple records at once.
- I concentrated on the data to excel conversion and vice versa.
Dynamics CRM 2013
- For a large company in the automobile industry I help to develop plugins and extensions for their Dynamics CRM system. We also maintaining and extending the CRM system for one of the largest manufacturers of cleaning equipment.
- We are working in a team of 12 and outsourcing work to 6 additional developers.
- I helped inventing a new JavaScript framework that optimizes the development process for CRM what will now be used by the whole company.
Dynamics CRM 2011
- For one of the largest manufacturers of cleaning equipment I help to develop plugins and extensions for their Dynamics CRM system.
- I try to optimize the development process in this team, based on my experience I obtained during my last projects. I also work on improving the output quality and quantity of the code.
Proof of Concept & Demo systems
- Occasionally I helped in the sales department with building demo systems and proof of concepts.
- Among other things I build a plugin that syncs SharePoint and CRM data, worked on a proof of concept with Google Glass, made two Windows 8 apps ֠one in C#/XAML the other one in JavaScript/CSS and a windows phone application.
Dynamics CRM 2011
- In this project, I developed extensions and plugins for an existing CRM solution for the leader in medical and safety technology.
- Apart from modifying the CRM system, I was the main developer for the client system. A WPF/XAML workflow application that syncs with Dynamics CRM.
Office 365 Connector
- In this project, I developed a WCF Service, which connects to Office 365 and manages the user roles, rights and licenses. To execute the actions, I used PowerShell scripts.
NopCommerce
- For a client, I had to modify the open source e-commerce platform NopCommerce. I have created additional plugins and widgets and changed the look and feel.
- In this project, I learned to orientate myself in a big and unfamiliar project.
Visitor Management Plug-In
- We developed a visitor management plugin for Outlook that helps optimizing the workflow of the reception. I was responsible for getting information out of Active Directory, writing information back and validating the input. I also was responsible for code reviews.
Mobility Dashboard
- In this project, we built a portal site, which was connected to different mobile device management solutions. The purpose was to manage all mobile devices from one portal and create extensible reports. My role was to build the frontend of the portal and connect to the service layer. I chose ASP.NET MVC 4 for the frontend and used LESS for styling. I also worked on jQuery extensions to provide more functionality for the end-user and helped fixing issues in the backend. When the backend developers where behind time slot I helped developing SQL-Queries.
Windows 8 Market App
- In my spare time, I built a Windows 8 market app that connects to SharePoint Online and displays recent news from different sites. The user can subscribe or unsubscribe to announcement lists. He can also categorize the news with different colors. The login to SharePoint Online works also with single sign-on and if the device isn't in the company domain the user can sign-in with a username and password.
- This app was the first app that provided a solution to connect to a SharePoint Online with an Active Directory Federation Service (ADFS) in front.
- I have sold a customized version of this app
University Dashboard
- For my seminar paper, I had to develop a dashboard for the intranet of the campus. I wrote the dashboard in ASP.NET MVC. It displays a variety of information depending on the current user. I used the exchange services to display mail quotas, actual size of the mailbox and the latest mails of the current user. I used Secure Shell (SSH) to get access to a Linux file server and display the users free disk space. And I connected to the print service to get the remaining print quota of the student.
Kinect PowerPoint Plug-In
- For presentation purposes, we developed a plugin that lets the moderator switch the slides with gestures. For the gesture detection, we wrote a framework in C# to quickly add new gestures.
Portfolio-Creator
- For my bachelor thesis, I developed a portfolio creator prototype in Silverlight that runs on SharePoint Online. The tools purpose was to deliver standardized files for a portfolio app that was designed for iOS.
Conception of a Portfolio-App for iOS
- Together with an external partner I made a concept of a portfolio app for both iOS and Windows 8. The first part of the app should reuse existing portfolios, help to organize them and give them a similar corporate design. The second part was to provide a tagging mechanism to quickly find needed information and create new portfolios from existing material. We used Scrum, with me being the product owner.
Web based plagiarism detection system
- This project was for the university. My colleagues and I developed a web based system to detect plagiarism in uploaded files. I was elected project manager and had to make the project planning and controlling. I used Scrum for the developing process. Also, I had to keep track of the progress and the working hours of the project members.
SharePoint XML-Migration Tool
- This tool had the purpose to migrate old InfoPath documents to a SharePoint Server by parsing the XML and editing fields that are specified by a template to provide the document functionality on the server.
SharePoint Dashboard-Web Part
- I built a SharePoint 2010 web part in Silverlight with animated tiles that could be configured to link to highlighted topics.
Active Directory Scanner
- In this project, I had to analyze the Active Directory (AD) and build a program that scans the AD very quickly. The UI had to display the structure of the AD, let the user navigate in the tree and follow group permission links.
C++ Jugend Forscht Projects
- Building a differential thermal analysis device that is controlled by a proportional-integral-derivative controller (PID controller). Winner in technology of the Jugend-Forscht competition (Region Baden-Württemberg/2006).
- Developing a camera based program to land an (model) helicopter. The program had to analyze the images provided by the camera, find the helicopter and send the helicopter new instructions based on the last known and the current position. Third place in technology of the Jugend-Forscht competition (Region Baden-Württemberg/2008).
