Custom Drupal module development
When custom modules are justified versus contributed ones or configuration, structuring services, hooks and plugins, and writing code that survives major version upgrades.
Drupal theming and development
Custom code on Drupal projects: building custom modules and themes, component-based theming, custom entity design, testing and code review practices that keep upgrades cheap.
Building a custom Drupal theme from Starterkit
Generating a new theme with the core Starterkit generator instead of subtheming a core theme, and why Olivero and Classy-based subthemes create upgrade debt.
Drupal Single-Directory Components for component theming
Organizing templates, CSS and JavaScript as Single-Directory Components with props and slots, reusing them across Layout Builder, Canvas and Twig templates.
Connecting a design system to Drupal
Bringing an existing design system or pattern library into Drupal through components, keeping tokens and markup in sync and governing changes across many sites.
Custom entity types versus content types in Drupal
Choosing between node bundles, custom content entities and configuration entities for business data, with consequences for revisions, translation, access control and Views.
Automated testing for Drupal projects
Testing custom Drupal code and critical user journeys with PHPUnit unit, kernel and functional tests, plus browser tests, static analysis with PHPStan and CI integration.
Drupal code review and coding standards
Reviewing custom Drupal code against Drupal coding standards and deprecation checks, a review checklist for agency handover, and enforcing standards in CI.
