Scope of Work

• Design, develop, and maintain Drupal‑based websites supporting DC.gov and District agency platforms.
• Build and customize Drupal modules, themes, content types, taxonomies, and views per agency requirements.
• Perform Drupal core and contributed module updates, security patches, and version migrations (e.g., Drupal 7 to Drupal 10/11).
• Integrate Drupal sites with enterprise systems, APIs, and third‑party services.
• Ensure deliverables comply with Section 508, WCAG 2.1 AA, and District web standards.
• Apply web security best practices consistent with federal cybersecurity guidelines.
• Collaborate with project managers, UX designers, content strategists, and agency stakeholders.
• Provide Tier 3 production support and participate in deployment activities, including occasional after‑hours work.

• Strong command of semantic HTML5: sectioning elements, headings hierarchy, lists, tables, and forms.
• Solid grasp of web accessibility (WCAG 2.1 AA): ARIA roles and attributes, keyboard navigation, focus management, alt text, and accessible form labeling.
• Familiarity with structured data and SEO markup: meta tags, Open Graph, Twitter cards, and Schema.org/JSON‑LD.
• Understanding of how Drupal renders markup through Twig, and the ability to produce clean, valid output via template overrides.

• Deep working knowledge of modern CSS layout:
  Flexbox and CSS Grid, with sound judgment about when to use each.
• Proficiency with responsive design: media queries, fluid typography, container queries, and mobile‑first methodology.
• Command of the cascade, specificity, and inheritance, with the ability to debug specificity conflicts rather than reaching for !important.
• Comfort with CSS custom properties (variables), modern color/spacing tokens, and maintainable theming patterns.

• Strong SCSS/SASS skills: nesting, mixins, functions, partials, and a disciplined file architecture.
• A consistent CSS methodology such as BEM, and an understanding of how it maps onto Drupal's class conventions.
• Familiarity with CSS transitions, transforms, and animations, used with attention to performance and reduced‑motion preferences.

• Solid command of modern JavaScript (ES6+): arrow functions, destructuring, modules, promises, and async/await.
• Strong DOM manipulation and event‑handling skills, including event delegation and performance‑conscious listeners.
• Fluency with the Fetch API and asynchronous data handling, including JSON parsing and error handling.
• Working knowledge of Drupal's JavaScript layer:
  Drupal.behaviors, once(), drupal
  
  Settings, and the AJAX framework.
• Understanding of how to attach and scope JS correctly through the Libraries API rather than inline scripts.
• Familiarity with debugging via browser Dev Tools: breakpoints, the network panel, performance profiling, and the console.

• Awareness of frontend performance: deferring/async loading, minimizing reflows, debouncing/throttling, and avoiding render‑blocking scripts.
• Experience with a build/tooling pipeline (Webpack, Vite, or Gulp) and with linting/formatting (ESLint, Prettier, Stylelint).
• Exposure to a modern framework (React/Vue) is a plus, particularly for decoupled or partially decoupled Drupal frontends.

• Fluency with the Drupal 9/10/11 admin UI: content types, fields, vocabularies, view modes, form/display modes, blocks, menus, URL aliases, and redirects.
• Solid command of Configuration Management workflows: config export/import,  for environment‑specific config,  for protected config.
• Strong grasp of user access control: roles, permissions, content moderation workflows, and custom workflow states/transitions.
• Demonstrated expertise with Views: complex queries, contextual filters, relationships, exposed filters/sorts, output rewriting, and REST exports.
• A clear mental model of what belongs in config vs. content vs. state vs. settings.php.

• Strong Twig skills: template suggestions, template preprocessing, and theme hook implementations.
• Comfort with the Libraries API: defining JS/CSS, managing dependencies, and conditional loading.
• Experience with…
