  • Optimize application and database performance.
  • Apply web application security and Oracle APEX security best practices.
  • Conduct unit testing, design walkthroughs, knowledge-transfer sessions, and post-implementation support.
  • Maintain project activities, tasks, and deliverables through Kanban or Azure DevOps boards.
  • Develop user guides, system documentation, technical procedures, and operational support materials.
  • Ensure solutions align with AODA accessibility requirements and Ontario government standards.
