  • Backend Awareness: Direct experience interacting with standard RESTful structures typically served by frameworks like Laravel, Express, or Django.
  • Design System Workflows: Direct experience working with Figma or similar (inspecting layouts, exporting assets, and understanding design systems).
  • Accessibility Compliance: Strong understanding of semantic HTML, ARIA attributes, and testing for WCAG 2.1 AA compliance.
  • Version Control: Proficient handling of code management workflows via Git and platform ecosystems like GitHub or GitLab.
