Worked on the SU-HSDO/suhumsci repository to deliver a Lando-based local development environment tailored for Drupal 10 multi-site projects. The work involved updating Lando configurations, introducing Bash and PHP scripts for database management and multisite setup, and aligning PHP and MySQL settings to ensure compatibility with Drupal 10. By restoring CI-related toggle module configurations, the developer reduced pipeline friction and improved onboarding for new contributors. The local development environment was designed to closely mirror production, streamlining setup procedures and enhancing developer efficiency. YAML was used for configuration management, supporting a smoother workflow for multi-site Drupal development and deployment.
