Building systems
that scale & endure

I'm a Product Security Engineer with 7+ years of experience in software engineering, now specialising in application security at NielsenIQ. My focus is on SAST, secure code review, and embedding security into the software development lifecycle across product teams.

Before moving into product security, I spent years as a Senior Backend Engineer and Technical Lead — building and scaling backend systems, leading cross-functional engineering efforts, and driving a security-first culture. I played a key role in achieving SOC 2 Type II compliance at Buy Me a Coffee, and led backend architecture for Voicenotes, an AI-powered voice platform.

My engineering background gives me a developer's perspective on security — making it easier to work with product teams, identify real-world risks, and deliver practical, actionable guidance.
