What I'm looking for

I am seeking a security role focused on proactive detection, threat intelligence and incident response within collaborative teams that value continuous improvement, stakeholder engagement and opportunities for technical leadership and growth.

I am a security professional with seven years' experience specialising in threat detection, incident response and risk management across enterprise SOC environments.

At Microsoft I serve as Security Engineer II on the Nuance team, liaising with clients such as HMRC and producing Domain Admin reports that improved privileged account visibility and compliance. I assessed threat intelligence capabilities, recommended CrowdStrike Recon+ and collaborated with MSTIC to strengthen SOC detections.

Previously I worked in CSOC and SOC roles at Arqit and Cyberclan/Cyjax, conducting application security assessments, BEC investigations and forensic analysis using tools like Burp Suite, Process Explorer and Hawk PowerShell. I helped design ISMS and ISO 27001-aligned controls, deployed deception using canary tokens, and led stakeholder reporting to translate technical findings into actionable risk reductions. I bring strong analytical judgement, cross-functional collaboration and a practical focus on proactive defence.
