Worked on the RuterNo/adt-doc repository to update Door API documentation in line with ADT2.0 standards, focusing on improving clarity for developers without altering existing API behavior. Addressed a key data integrity issue by enforcing MessageNumber as a required field for Door and Door Individually endpoints, thereby preventing potential inconsistencies in backend data. Utilized Python for backend changes and Markdown for comprehensive documentation updates, ensuring that onboarding and integration processes remain straightforward for new developers. The work demonstrated a methodical approach to API development and documentation, balancing the need for reliability with minimal risk to current client integrations.
