Complexity in.

A system means
nothing until
someone uses it.

Security analysts don’t need another dashboard.
They need a reason to come back.

$ whoami

Curious by default.
Hands on, always.

I still write code. It keeps me close to the problem, the people using the product, and the details that make it work.

Now: cybersecurity product engineering at Visa.
