This is a project I still announce when meeting with clients. Now because I have built it, but because 3 years later the job I did for trans-les.com make around 2000-3000 new potential clients a months.
This project helped me learn how SEO works and how to implement it. This project can be found on 1st place in Google with local keywords.
The technologies and programming languages I used: PHP, JavaScript, Ajax, jQuery, HTML5, CSS3, MySQL, Bootstrap, PDO, OOP,
