Jeremy Kendall


I’ve been developing for the web since 2001, taking a special interest in best-practices and test driven development. While I develop primarily in PHP, I’ve had some significant experience with Java, and have dabbled in many other languages including Ruby and JavaScript.

Community Involvement

Open Source Libraries Authored

I have authored several popular open source libraries:

  • PHP Domain Parser: Public Suffix List based domain parsing implemented in PHP.
  • Query Auth: Signature generation and validation for REST API query authentication.
  • Password Validator: Makes upgrading to secure password hashing both simple and easy.
  • Slim Auth: Authorization and authentication for the Slim Framework.

At various times I have contributed to:
