Multisite WordPress Platform

A WordPress multisite built for a travel agency with a unique custom-made theme and plugins.

I was the team lead and senior developer, and working closely with the team, we were able to build a platform that allows the agency to create, promote, and sell their tours across their multisite. It also helps them follow every step of their clients to bring them the best experience in the process.

Website for a Montreal Real Estate Agency

The website is also integrated with the provider of their listings (Centris) which allows them to get automatically daily updates of their properties, reducing the administration work considerably.

I was the front-end and back-end developer for this project.
