My Learning
In this course, I gained practical experience with Identity and Access Management (IAM), learning how users, groups, and roles work together to manage permissions securely. I wrote and tested JSON policies that enforce the principle of least privilege to limit access based on roles.
Comparing cloud service models helped me understand the trade-offs between control and convenience. With IaaS, customers manage more components like the OS and runtime for greater flexibility, while serverless (AWS Lambda) reduces operational work, letting developers focus on code and data.
The AWS Shared Responsibility Model clarified what AWS secures (data centers, hardware, networking) versus what users secure (configuration, access, and data). I practiced encrypting data in transit and at rest, reviewed safe S3 access policies, and used AWS Config to monitor compliance.

Favorite Technology
My primary focus is AI Security. I’m currently completing AI Security Fundamentals by Security Ignite to strengthen my understanding of model and data threats, prompt and jailbreak defenses, and secure deployment practices. I’m especially interested in applying principles like threat modeling, least privilege, and defense-in-depth to AI systems.
Hobbies / Interests
I enjoy sports—playing, watching, and following highlights. Outside of sports, I read regularly; right now I’m reading AI in Security to connect technical concepts with real-world applications. I also enjoy building small projects and sharing what I learn with friends and classmates.
Generative AI Video Experiment
Tool: Veo 3. I generated this short clip from a text prompt describing a high‑stakes indoor swim meet in cinematic slow motion with above‑ and below‑surface shots, overhead tracking along the lane lines, and a dramatic final wall touch. I referenced my face for likeness and aimed for realistic motion blur, natural lighting, crisp reflections, and film‑style color.
- What I controlled: camera paths (glide/underwater/overhead), pacing that builds to the last lap, and subject focus (eyes under goggles, surface breaths).
- Why it matters: demonstrates how Veo can visualize action, water physics, and identity‑consistent shots for portfolio storytelling.
