Justin Hall


Hi, I'm Justin.

I'm a full-stack developer dedicated to crafting great user experiences with trusted technologies like React, Node.js, and PostgreSQL.

While I've used a wide variety of different tools, libraries, and frameworks, some of my favorites include: TypeScript, JavaScript, GraphQL, Express, Gatsby, Next.js, Jest, Cypress, XState, Emotion, Tailwind CSS, ESLint, Prettier, Docker, and Git.

Check out some of my work:

Password Lense

Certain characters in passwords ('O' and '0', 'I' and 'l', etc.) can be hard to identify when you need to type them in (and copy-paste is unavailable). Password Lense is a small web application that provides a quick and secure way to get a more informative view of your password.
