About Me

Securing systems.
Building solutions.

I'm a cybersecurity and IT professional based in Leicester, UK, with a Master's degree in Cybersecurity from Sheffield Hallam University. My work sits at the intersection of security operations, IT administration, and proactive threat management.

Currently leading a comprehensive security transformation of a Microsoft 365 environment at Kaine Management, covering Conditional Access, MFA enforcement, Defender for Endpoint, and DLP policy design.

Beyond security, I freelance as a developer, building web applications, mobile apps, automation workflows, and Chrome extensions that solve real-world problems.
