During February 2026, Bart developed an Office365 Graph API Email Backend for the open-formulieren/open-forms repository, enabling the application to send emails through Office365 using the Graph API. He implemented a robust API integration in Python with Django, focusing on backend development to enhance email delivery reliability and scalability for Office365 users. Bart designed a configuration flow that allows administrators to set up the new backend efficiently and updated the installation documentation to guide users through the process. The work addressed the need for a modern, scalable email solution, demonstrating depth in API integration and backend architecture within a short timeframe.
