What I'm looking for

I'm open to remote and freelance opportunities where I can build practical security tooling, strengthen threat detection and incident-response capabilities, and apply full-stack and AI/ML skills.

I've designed, developed, and deployed 11 production-grade cybersecurity projects, including incident response simulators, phishing detection models, port scanners, and encryption tools.

My SOC Incident Response Simulator provides 30+ MITRE ATT&CK-tagged scenarios for analyst training, while my phishing classifier reaches 94% precision and 91% recall using scikit-learn. I've also built a parallel TCP port scanner with CVE correlation and a hybrid file-encryption tool using AES-256-GCM and RSA.

Alongside freelance security development, I evaluate large language model outputs for Outlier AI, perform quality assurance, and use prompt engineering to analyze edge cases. I'm building my cybersecurity and digital forensics foundation through my degree studies.
