Pilcrow

Hi! I'm a software developer in Tokyo interested in auth and application security. I love thinking through tiny details and creating things from scratch. Some of my other hobbies are cooking, taking photos, and traveling.

Here are some projects I've worked on:

• basic-example.auth.pilcrowonpaper.com: An example website that implements email address and password authentication following best practices.
• Lucia: Former NPM package and current JavaScript/TypScript learning resource on session management.
• Arctic: An OAuth 2.0 client NPM package.
• Oslo: A collection of auth-related NPM packages including packages for cryptographic-operations and the web authentication API (passkeys).
• The Copenhagen Book: A general guideline on implementing auth in web applications.
