What most organisations really need is someone who can step in with real technical authority and accountability. Someone who leads the team and makes the calls that achieve business outcomes. That’s the role I step into.

Someone accountable for your tech

I own the technical direction of your organisation and take accountability for it.

The right expertise for your business

I’ve been inside 250+ tech projects and can identify what’s about to go wrong before it does.

A leader your team and vendors can work with

I can run your engineering function not as an advisor, but as the person your team reports to and your partners answer to.

Someone who can translate both ways

I speak to your leadership team in business terms and your engineers in technical ones. You stop being the person in the middle trying to bridge the two.

An engineering team if you need one

If you don’t have engineers, I bring mine. 26 people across software, AI, cloud, security - people I’ve worked with for years.
