Tunisian Army (IT Division)

Senior Software Engineer

Tunis, Tunisia

Joined a team of developers to help stabilize and maintain a complex HR system. I was primarily in charge of the training and education product. The system was built in PHP 4 for the back-end. After consulting my team, I decided to migrate the application to PHP 5 in the first step which later evolved to migrating to version 7 after it was released near the end of 2015. The original application did not use any framework and I decided to migrate it to Laravel. The original code base was a monolith with large files and lacking OOP good practices. I drew a plan on how to migrate the code while keeping the application (web + API) backward compatible. With my team, we covered 55% of the code base with unit tests to grow our confidence in the transition. I have trained a team of 4 developers on how to adopt good quality practices like: reusable components, OOP, single-responsibility methods, dependency injection, use of ORMs, protection against SQL injection and cross-site injection, etc. I have worked with another developer on converting vanilla views to blade files.

Although the application is only used by approximately 50,000 users everyday which may not require scalable resources. Nevertheless, I deployed resources in 3 regions to allow replication and improve availability.
