About

The person behind
the practice.

PrsnQA is one person, fully accountable — not a team of contractors with a senior face on the pitch.

Stuart Coulson — Founder, PrsnQA

Stuart Coulson

Founder · PrsnQA

I'm a senior QA professional with twenty years of experience leading test functions across complex, high-stakes technology programmes. That spans enterprise pricing platforms, delegated underwriting systems, finance transformations, and AI-assisted tooling — at firms including Liberty Specialty Markets, Munich Re, Allianz Global, and Convex Insurance.

What that time teaches you is the difference between testing that looks productive and testing that actually reduces risk. Most teams are good at the former: the metrics look healthy, the coverage numbers are high, and then something breaks in production that nobody saw coming. The real work is building the quality infrastructure — strategy, automation, release governance — that gives your team genuine confidence, not just numbers.

PrsnQA exists because senior QA leadership doesn't have to mean a full-time headcount commitment. I work as a fractional Head of Testing — embedded in your tools, your sprints, and your planning cycles — so growing engineering teams get the strategic oversight that was previously only available to enterprises. UK-based, working remotely across time zones.
