Each figure links to the write-up it came from, including how it was measured. Numbers without a client and a source are marketing, not evidence.
What people call me about
EngagementsEvery senior technology decision lands on one person, and that person is running out of hours.
Fractional CTO
You're weighing an acquisition, and the code is the part nobody in the room can read.
Technology due diligence
You're scaling faster than the architecture was built for, and you need to know what breaks first.
Architecture and security reviews
Your engineers are using AI tools, and nobody agreed on what good looks like.
Agentic development and AI adoption
Your leadership team keeps having the same argument about direction, and it never quite resolves.
Technology strategy workshops
You have good engineers who've stopped growing, and no one senior enough to pull them up.
Engineering leadership development
The thing needs building, and standing up a permanent team to build it is the wrong shape.
Software development
Clients
Ligentia/
Billion-pound enterprises and two-person startups, usually at the point where a technology decision has become too expensive to get wrong.
