What I'm looking for

I seek a hands-on security role where I can apply my cybersecurity certifications and DBA experience to detect threats, respond to incidents, and improve security posture.

I am a motivated cybersecurity professional recently certified in Security+, SyCA+, and CSAP, bringing a strong foundation in threat detection, incident response, cryptography, network security, and secure architecture. I pair hands-on cybersecurity training with extensive experience as an Oracle Database Administrator, where I supported production environments, tuned performance, and provided 24x7 on-call incident support.

My achievements include practical experience managing multiple database environments, resolving data quality and integrity issues, and collaborating with developers to design secure application-data integrations. I am prepared to apply my training with tools like NMAP, Wireshark, Metasploit, OWASP, Ettercap, and Kali Linux to strengthen organizational security posture and respond effectively to threats.
