What I'm looking for

I'm seeking an entry-level cybersecurity role where I can apply my technical expertise, analytical mindset, and passion for digital safety.

At Institute of Data, I reviewed and assessed student lab work across threat analysis, network scanning, vulnerability assessments, and server hardening. I also supported students with Linux, cybersecurity tools, and NIST compliance frameworks.

During my Institute of Data lab internship, I investigated malicious URLs and phishing emails, triaged security alerts, and analyzed packet captures with Wireshark. I ranked in the top 4% of the Huntress 2025 CTF, and my earlier work at Speed & Stracey Lawyers involved handling confidential client data and supporting security protocols.
