Worked on updating the Airflow 3 Architecture Overview for the astronomer/airflow repository, focusing on documenting the new architecture with an emphasis on Dag bundles and component separation to enhance security and scalability. Collaborated closely with other contributors to ensure the documentation aligned with cross-team requirements and provided clear architectural guidance for both customers and engineers. Utilized reStructuredText for technical writing and documentation, applying architecture design principles and version-control best practices to maintain traceability of changes. The work improved maintainability and security posture by clarifying component roles, resulting in more accessible and actionable documentation for the Airflow engineering community.
