Mission

The context

Design and development of the web platform for Groupe Drapeau, a civil engineering, construction equipment rental, and real estate company in Togo.

I took charge of the entire project: architecture, fullstack development, server configuration, performance optimization, and security best practices on the production side. The role also included product coordination with management.

The source code is public on my GitHub. The mission concluded with a complete transfer to Groupe Drapeau's internal team for corrective and evolutionary maintenance.
