Quality that's assured, not assumed.

What I bring

A tester who can lead the team as well as find the bugs.

I plug into your delivery team quickly and take ownership of quality, from refinement through to release.

Test leadership

Leading small test teams on high-value programmes: planning coverage, prioritising risk and keeping delivery honest about quality.

Agile & Scrum transformation

Moving teams from waterfall to a working Scrum cadence, with sprint planning, 3 Amigos and retrospectives that people actually find useful.

Functional & exploratory testing

Structured and exploratory testing that follows real user journeys and finds the problems scripted checks miss.

Regression & release assurance

Repeatable regression packs and clear go/no-go evidence, so every release goes out with confidence.

Test management tooling

Setting up Jira, Confluence and qTest to create, run and track tests, with traceability the whole team can see.

Stakeholder alignment

Bringing suppliers, consultancies, permanent staff and contractors into one well-organised delivery rhythm.

Government

Multi-supplier Scottish Government programmes handling sensitive casework and wellbeing data.

Banking & Financial

Testing in regulated environments where accuracy, auditability and resilience are non-negotiable.

Broadcast & Media

Consumer-facing platforms at STV where uptime and user experience reach a national audience.

How I work

QA should shape the product, not just guard the exit.

“Treating QA as a barrier to production is the quickest way to ship a half-baked product. Bring a QA mindset into every stage and quality becomes the goal, not the defender.”

— Calvin Neilson, on shift-left testing

  1. 01

    Involve QA from day one

    I join refinement, question requirements and break user stories before a line of code is written.

  2. 02

    Quality is the goal, not the gate

    When the whole team has a QA mindset, testing stops being the final hurdle and becomes how the product gets built.

  3. 03

    Clarity over ceremony

    Everyone should start a sprint knowing exactly what they're building and how it will be proven.

Track record

From apprentice tester to contract test lead.

In October 2021, aged 23, I went independent and founded CRMN Tech Ltd. I went on to spend four and a half years delivering Scottish Government programmes through successive contract renewals.
