The work

01

From legacy complexity
to momentum.

I operate where strategy, organisation and architecture meet: restoring reliability in financial services, integrating teams after acquisition, and improving delivery outcomes in high-traffic technology environments.

The common thread is simple: build the conditions for talented people to deliver better work, with technology that makes the business more capable.
