Quality engineering leadership. Reliable releases.
AI workflows that work.

I help technology teams improve software quality, shorten feedback cycles and verify that AI agents complete the tasks customers rely on. I bring 14 years in software quality and engineering leadership, including roles at The Economist, Reapit and Smartcat, alongside hands-on experience building products and businesses.

Available for remote consulting engagements, defined projects and fractional quality leadership.

01Experience

Quality leadership across established products and
AI platforms.

Selected roles at

  • The Economist
  • Reapit
  • Smartcat
  • Cotality

02Selected outcomes

What that experience looks like
in practice.

  • Reapit: faster regression feedback across desktop and API testing.

    I led QA across the UK and EMEA as we moved desktop automation from TestArchitect to FlaUI and added Playwright API testing. A full automated desktop regression run dropped from about 15 hours to 1–2 hours.

  • AI evaluations: checking that the task actually happened.

    I reviewed and improved evaluations that could reward a convincing answer without verifying the completed action. The work strengthened assertions, reduced failures caused by unstable tests and made workflow outcomes easier to investigate.

  • The Economist: quality across mobile apps and their content platform.

    I led quality across The Economist and Espresso apps and the wider content delivery platform, combining close product and engineering collaboration, layered automation, integration testing and performance and stability checks on physical devices.

03Consulting

Three ways I can
help your team.

  1. Improve test reliability, release confidence and delivery feedback. Bring me in for a focused assessment, a defined improvement project or ongoing leadership alongside your engineering team.

  2. Verify completed actions, tool use, handoffs, recovery and approval handling. Build evaluations that help your team understand what failed and decide what is ready to release.

  3. Scope and build a product, or automate a repeatable business process. My own ventures bring practical experience of product decisions, implementation, launch and ongoing operations.

04Engagement

A focused assessment, a defined project or
a fractional role.

We agree the problem, outcomes, responsibilities and fees before work begins. I work remotely with your team, with collaboration hours and involvement agreed around the engagement.

What does your team
need to improve?

Tell me about your release process, quality challenges or AI workflow, and the support you need. I’m available for remote consulting, project work and fractional quality leadership.
