Worked on the mealie-recipes/mealie repository to enhance multi-group recipe management by implementing group-scoped sub-recipe resolution using slugs. Addressed the challenge of identical slugs across different groups by ensuring sub-recipe references are resolved only within their respective groups, which improved data integrity and reduced cross-group conflicts. Developed robust error handling for cases where referenced recipes do not exist in the current group, supporting more reliable and scalable enterprise-style recipe reuse. The solution was delivered through maintainable backend changes using Python, with a focus on API development and thorough testing to ensure reliability and ease of future maintenance in multi-tenant environments.
