Tools and practices

A working set of tools and practices I use to turn product ideas into clear, maintainable web experiences.

  1. Product UI: I build product interfaces with React, Next.js, TypeScript, Redux, and TanStack Query.
  2. Systems & motion: I shape reusable systems with Tailwind CSS, Chakra UI, Storybook, GSAP, and Framer Motion.
  3. Content & data: I connect content and data through WordPress, Gutenberg, PayloadCMS, REST APIs, and third-party integrations.
  4. Performance & delivery: I ship for performance with Core Web Vitals, accessibility, Jest, CI/CD, and esbuild.
