Securing systems end to end, from governance and offensive testing through to applied machine learning.
Defence on three fronts.
Security operations
ISO 27001 compliance, endpoint and patch management, access control and incident response across live production estates.
Offensive security
Web application penetration testing and red teaming, reported with reproduction steps, risk ratings and remediation guidance.
AI security & research
Deep learning for malware detection: cutting false alarms without losing real threats, and making the model explain its verdict.
About
work at the intersection of cybersecurity and machine learning — two disciplines that, combined, produce more capable and resilient defensive systems than either achieves alone. My MSc dissertation extends a 2018 ANN baseline to reduce false positives in deep learning-based malware detection using memory forensics, applied to the CIC-MalMem-2022 dataset in PyTorch.
Before Plymouth, I spent time as an IT Administrator at Fcode Labs, supporting ISO 27001 compliance activities, managing endpoint security, and building an asset management tool with Microsoft Power Apps. I also completed hands-on penetration testing at Hacktify Cyber Security — web application vulnerabilities, red teaming, and CTF challenges — alongside IT engineering roles at Kingslake and South Asian Technologies.
I care about work that is honest about its limitations, measurable in its impact, and documented clearly enough to be understood by someone else.
