Hi! 👋

Who am I?

I’m a security & data privacy enthusiast specialising in building security for tech startups.

I’ve had various security oriented roles for the last 7 years, ranging from cloud security engineering to compliance leadership positions.

As a security leader who understands the importance of reducing cognitive load & improving developer efficiency, I’ve always worked to ensure my teams are embedded in the wider engineering departments we’re in, so we can share the same pains, and as a result, successes too.
