About Me

I am a cybersecurity professional with over 5 years of experience, specializing in blue team operations, security solution deployment, incident response, and threat hunting.

With a strong foundation in network and system administration, I am now aiming to move into a leadership role (Manager/Team Lead) where I can combine my technical and analytical expertise to guide teams, shape security strategies, and drive organizational success. I hold a Bachelor’s degree in Computer Science from BINUS University Online Learning, graduating with a GPA of 3.95.
