About Hassan

Currently pursuing a Master's degree and working as a systems engineer at Université Paris-Dauphine, I have been deploying web servers in production for several years: IIS on Windows Server, Apache2 and Nginx on Linux Debian, with HTTPS configuration (Let's Encrypt), reverse proxy, virtual hosts, and MySQL/MariaDB databases. I offer my freelance services for any targeted mission: website deployment, server security, or configuration. Serious, autonomous, and responsive.
