What Others Think
"Arda came in and just got things done. Updated our entire cable documentation without needing to be told twice — found errors in the port records that had been sitting there for months. Kid knows his way around infrastructure."
"Honestly didn't think anyone in our year would set up a full GNS3 lab on their own. The CDL project was on another level — he had Kali running attacks against a simulated network while the rest of us were still configuring basic routing. Respect."
"The PhishSense material genuinely made me stop and think before clicking links. It doesn't feel like a boring security lecture — the examples are actually realistic and the explanations click. I forwarded it to my whole family after."
"Arda consistently goes beyond the curriculum. He approaches problems the way you want students to — first understand, then build. His lab work shows genuine technical depth, not just surface-level execution."
"bro explains wireshark like it's the easiest thing in the world and then you realise you've been learning for an hour without noticing. also fixed my router config in like 10 minutes when i was completely lost. goat behaviour."
"Always the one in the room who actually knows how things work. I remember asking him why my laptop kept dropping WiFi and he diagnosed it, fixed it, and explained the reason in under two minutes. It's kind of annoying how good he is."
