Consultancy

Partnering with teams on complex software.

Architecture, delivery and modernisation, for organisations where the software carries real weight. Public services, national retail, trading platforms. We take on whole builds, and we work inside teams that already have momentum.

Track record

Every engagement, in full

This is Phil Davies' history rather than the company's. It spans permanent roles in the nineties, an earlier company, and contracts run through Cool Unlimited, and each entry says which it was.

It is here in full rather than trimmed to a summary, because the range is the useful part. Government estates and trading systems, yes, but also a hand-rolled HTTP proxy and a rail network optimised by genetic algorithms.
