Welcome to my digital home! I am a highly skilled software developer with a master's degree in computer science, specializing in both front-end and back-end development for business applications. Beyond the world of coding, I also lead worship at my local church, channeling my passion for music. As an advocate for open-source software, I contribute to the collaborative and innovative world of tech. Occasionally, I share my insights and experiences through blogging.


Projects

ChurchTools API Wrapper

Open Source

ChurchTools provides a REST API for data exchange. This project and the resulting API wrapper make the API easier to use. The wrapper was written in PHP to simplify integration into Wordpress, Nextcloud and other PHP-based systems.

5PM Worship Tool

Open Source

The 5PM worship tool was created for the bands in the 5PM service. By integrating the ChurchTools API, musicians can log in with their ChurchTools account and use the tool. The management of sheet music, a separate "rehearsal tool" and the display of wiki pages are the central functions of the tool. All data is retrieved directly from ChurchTools.

Note-Writer

Open Source

The content of my student research project was the classification of note values of a melody that was played via a web-MIDI interface. The classification is carried out using machine learning algorithms. A YouTube introductory video was also created as part of the work.
