I have included some sample files from various projects that I have worked on.
This project is from circa 2015 and is still one of the largest PHP projects I have undertaken although it is from a time much earlier in my web development career. The initial version of this website was created without the use of any frameworks although I soon migrated it over to CodeIgniter. The website was a custom eCommerce website for a prepared meals startup in Toronto. It used the Stripe API to manage transactions.
