PHP and JavaScript Programming

Welcome to Onyx Coding

My name is Sean McCartan, and I'm the owner of Onyx Coding. For over five years now I've been a developer working mainly with the programming languages of the internet - JavaScript, PHP, HTML, and CSS. I've also worked extensively in WordPress and Joomla - two of the most popular content management systems (CMS) in the world. I also have considerable experience working with React, MySQL, and have spent many hours in server environments on Linux based operating systems - performing tasks such as updating packages, managing security, and doing custom scripting.

My focus tends to be on PHP and JavaScript web development, but if you are in need of a developer who's skilled in any of the areas mentioned above - please get in touch using my contact form, or send an email to This email address is being protected from spambots.
