What I'm looking for

I am looking for a challenging role that leverages my technical skills and leadership abilities to enhance organizational security.

I am a results-driven Cybersecurity Engineer with a proven track record in designing, implementing, and managing robust network security solutions. My expertise lies in Network Access Control (NAC), networking protocols, and threat hunting, with a strong focus on securing critical assets. I have successfully reduced security incidents by 20% through comprehensive security solutions and improved incident response times by 25% using advanced analytic methods.

Throughout my career, I have demonstrated a commitment to enhancing organizational security postures. At Homebridge Financial Services, I led the integration of CI/CD pipelines, significantly reducing deployment times and improving consistency across environments. My experience includes managing SIEM tools like Splunk and Grafana, which enhanced real-time monitoring capabilities. I am proficient in the NIST CSF Framework and Zero Trust Infrastructure, and I have a strong background in incident response, encryption, and network security.
