Mitchell Dsilva enhanced code ownership and UI quality across the ministryofjustice/hmpps-activities-management-api and ministryofjustice/hmpps-activities-management repositories. He introduced and refined CODEOWNERS files, automating pull request reviews and clarifying accountability by aligning ownership rules with the development setup, including Dockerfile.local. Using skills in CI/CD, DevOps, and frontend development, Mitchell streamlined code ownership management and removed unused references to improve maintainability. He also fixed a UI typo in Nunjucks templates, ensuring grammatically correct attendance options. His work, primarily in Kotlin, Nunjucks, and YAML, improved developer experience by enabling faster reviews and more maintainable, clearly owned codebases.
