Leadership & quality strategy

I set the standard, then build the system that keeps it.

Beyond writing tests, I shape how whole organisations think about quality.

Company-wide QA strategy

Set QA strategy and standardised processes across the company, establishing governance where none existed.

Quality metrics for leadership

Report quality to engineering leadership through live Grafana QA dashboards fed by automated test results.

Line management

Led three QA engineers across all testing activity, owning their growth and career paths.

Hiring & mentoring

Interview and hire QA engineers; onboard, train and mentor new joiners.

Early adopter · AI in QA

An AI-assisted test practice, shipped company-wide.

At Miele X I initiated and shipped the AI-assisted test development practice: custom QA agents that generate and maintain test code, governed by the coding standards, patterns and skill instructions I authored. It's how the QA team works every day.

Experience · 2014 to today

Six teams. Each one shipped with more confidence.
