@wailboudiaf
I am a Network and Systems engineer passionate about cybersecurity and technical support.
I am a Network and Systems engineer with hands-on experience in network technologies, cybersecurity and technical support gained through internships and freelance work. I focus on building reliable, secure IT solutions and providing pragmatic support to users.
As a freelance technician I install and configure SSL (Let's Encrypt, Cloudflare), troubleshoot SMTP and email delivery issues, provide remote technical assistance, and build simple landing pages using HTML/CSS and React. I prioritize clear communication and fast, effective fixes for clients.
During stages at MOBILIS and ALGÉRIE TÉLÉCOM I worked with mobile and fixed infrastructures (2G/3G/4G, FTTH, DSLAM), participated in incident ticketing and field configuration tasks, and supported maintenance and connectivity testing. I also handled administrative data management and ensured data backup and restoration.
I hold networking and cybersecurity certifications (including CCNA and Fortinet Cybersecurity training) and use tools such as Cisco, pfSense, Kali Linux, Burp Suite, GNS3 and virtualization platforms. I am serious, autonomous and motivated to grow technically while contributing to secure, scalable network operations.
