What I'm looking for

I seek a security-focused role where I can perform penetration testing, harden systems, and contribute to a collaborative team that values precision, continuous learning, and measurable impact on risk reduction.

I am a detail-oriented computer security enthusiast with hands-on experience in penetration testing, vulnerability scanning, and secure application development using Python. I have supported network and hardware troubleshooting while applying systems knowledge across Windows and Linux environments.

During an internship at Webseal International I assisted in penetration testing and reporting, contributed to secure application development, and performed database and system analysis. I have also worked extensively on data annotation projects, achieving high accuracy and improving model performance through rigorous quality control.

I bring strong analytical thinking, attention to detail, and time management to fast-paced security and data roles. I stay current on cybersecurity trends and seek opportunities where I can protect digital assets and contribute to robust security practices.
