Experience

Event-oriented Content Management System

This product is a content management system with an integrated shop and tools for event planning and execution. It’s built with Angular and ASP.NET Core with Microsoft SQL Server. The platform is designed for internal use and will be launched as a product for customers. I contributed most of the code and served as the main (at times only) developer on the project.

Software for Visualizing Emotional and Genetic Relations

This software is used to visualize complex emotional, genetic, and legal relationships to understand an individual’s perspective. This project is a successor to an existing project and is now a web application accessible on notebooks and tablets. I was the front-end developer on the project.

This product helps automate and simplify the company’s specific workflow. It keeps track of the inventory and the value of the inventory as well. It also communicates with other software like SAP to sync the information and update its webshop.
