Projects

PHP Laravel FilamentPHP Tailwind CSS SQLite Docker Portainer Caddy Traefik

I created an internal administrative system used by about 100 employees of ZSE. This system allows for managing employees, students, contests, achievements, scholarships, applications, malfunctions, and room reservations. This project was a great opportunity for me to learn new technologies (Laravel and FilamentPHP) and to deploy a real system on a physical server ("bare-metal"), using Portainer, Traefik, and Docker among others. I also had to ensure proper security and authorization for different employee access levels, as well as the overall reliability of the application.
