Networks and telecommunications engineering student who builds infrastructure and then secures it.
seeking a networking, security or systems internship
Profile
I build infrastructure and then secure it. Contest networks deployed from bare rooms — cabling, switching, addressing plans and DHCP for 250+ participants — Linux administration, and daily practice in traffic analysis and reconnaissance.
Webmaster of Securinets, Tunisia's largest cybersecurity association, where I ship and operate the platforms behind national CTFs and hackathons — 4 CTF platforms and event sites totalling 50,000+ visits, all of them mine to keep online when registration spikes.
Competitive programmer with 5 medals and 7 top-10 finishes across 10+ contests. Currently seeking a networking, security or systems internship in Europe.
