Hi, I'm Justin.

I'm a software developer with an affinity for the web, dedicated to crafting great user experiences with proven technologies like React, Node.js, and PostgreSQL.

While I've used a wide variety of different languages, tools, and frameworks, my current favorites include: TypeScript, XState, Remix, Tailwind CSS, Prisma, Vite, Vitest, Cypress, ESLint, Prettier, Docker, and Git.

Check out some of my work:
