Project Title: Les Éclaireurs Solidaires – Mutual Aid and Solidarity Web Platform

Project Description:

Full-Stack development of a citizen mutual aid and solidarity web application, designed to connect volunteers and people in need. This major project served as technical support for the validation of my professional title as a Web and Mobile Web Developer (DWWM). I designed the entire platform, from database modeling to software architecture and responsive integration.

🛠️ Technical Skills & Stack Used:

Architecture & Back-end: PHP (Custom MVC Architecture), Object-Oriented Programming (OOP).

Database: MySQL / SQL (Design and modeling of a complex 11-table relational structure).

Front-end: HTML5, CSS3, JavaScript (Creation of a dynamic, fluid, and 100% responsive user interface).

Web Security: Implementation of advanced security protocols (protection against SQL injections via prepared statements, XSS vulnerabilities, and CSRF token form security).

🚀 Technical Challenges Met:

Complex Modeling: Structuring an optimized relational database to manage users, mutual aid listings, categories, and real-time interactions.

Enhanced Security: Application of OWASP best practices to ensure the protection of the platform's user data.

User Experience (UX): Careful integration offering intuitive navigation on both mobile and desktop.

In Corys' R&D operations team, composed of 4 developers out of 18, my goal was to debug in C++, Qt, and Windows batch files on various projects. I had to manage over a hundred observation sheets, including the use of the C runtime library (CRT) heap debugging functions method which dumps memory leaks in all compilation modules, formatting the new User Interface (TsmMgr), which is a Qt-based application, with existing code, adapting the code during the x64 migration (moving from Windows 7 VC10 to Windows 10 VC14), using the (Qt Language) library which manages the different languages of the Application. This experience allowed me to discover the Windows environment, configuration files with keywords that will be called in the C++ code, to learn about the use of batch files, and Perforce which is the resource management system, to gain skills in C++ and Qt, especially to work in a very large dynamic team and to be introduced to the field of dynamic train simulation.

Crane Manufacturing. The objective of this mission is to correct all bugs reported by the Development teams on the displays of various cranes and to develop a library that manages the fault codes of the two ECUs (CCT and SCM) from an SQLite database. In this team of 3 developers in an agile environment, my objective was focused on the display screen of the Hammer Head Tower Crane (GME). Among the tickets I managed, I developed:

• The counters page using a QTabWidget that allows switching from one sub-page to another.

• The display of the Quick Lock page (which is a notification).

• The display of the padlock (linked to the SCM startup).

I developed the fault code library on the Qt C++ side and also developed tests in parallel.
