Glad to anounce that I've successfully passed my OSCP exam held by @offsectraining 👏🏻

Excited to share that I just passed the Certified Artificial Intelligence PenTest Junior (CAIPJ) exam! 🎉 The experience was eye-opening and honestly a lot of fun. I went in expecting the usual web app vulnerabilities, but was surprised by how deep and creative AI can get.

I’m happy to share that I’ve obtained a new certification: Certified Cybersecurity Educator Professional (CCEP) from Red Team Leaders!
