Naila Tinsalhi developed architectural documentation and an Architectural Decision Record for backend-driven diagram layout customization in the eclipse-sirius/sirius-web repository. She focused on defining extensibility for diagram rendering by enabling backend-controlled layout logic and supporting custom post-processing. Using Java and adoc, Naila documented the problem space, outlined user needs, and proposed a solution, culminating in an iteration plan to guide future enhancements while minimizing integration risks. Her work emphasized architecture and backend development, establishing clear documentation standards to support maintainability and future feature delivery. This foundational effort provided depth in design and set the stage for extensible backend-driven rendering capabilities.
