What I do

Design

  • User interviews and personas
  • Task-based usability testing
  • Interaction design and wireframes in Figma
  • Design systems, from Figma to Storybook
  • Accessibility to WCAG 2.1 AA
  • Brand identity and art direction

Engineering

  • React, Next.js and TypeScript
  • Tailwind CSS and Sass
  • Supabase, Postgres and Prisma
  • Payments, email and CMS integrations
  • Drupal 9 and 10, PHP
  • CI/CD with Azure Pipelines and GitHub

Because I work on both sides, designs arrive at development already shaped by what the platform can do, and nothing gets lost in a hand-off document.
