What is a fractional CTO, and do I need one?

A fractional CTO is a senior technical leader who works part-time across one or more companies, typically one to two days a week. You likely need one if your team is shipping software but has no senior engineering voice in the room — for hiring, architecture, security, roadmap and tough technical decisions.

How much does a website accessibility audit cost?

A small marketing-site WCAG 2.2 audit typically starts around £1,500, with larger product audits in the £4,000–£10,000 range depending on the number of templates, components and user journeys. Every engagement includes a prioritised issue list and a remediation plan you can hand directly to your developers.

What is WCAG 2.2 and does my site need to comply?

WCAG 2.2 is the current Web Content Accessibility Guidelines standard. In the UK, public-sector sites are legally required to meet WCAG 2.2 AA under the Public Sector Bodies Accessibility Regulations 2018. Private-sector sites are expected to be accessible under the Equality Act 2010 and increasingly under the European Accessibility Act from June 2025.

How long does a website performance audit take?

A typical performance audit takes one to two weeks: lab testing against Core Web Vitals, field-data review from real users, render-path analysis and a written report with prioritised fixes. Urgent engagements can be completed in a few days if the site is small and the issues are obvious.

Do you work with teams outside the UK?

Yes. chrimes.dev is remote-first and based in Leeds, UK, working across UK and European time zones. Most engagements happen over video calls, shared docs and pull requests. I travel to clients in person for kick-offs and workshops when it helps.

What technology stacks do you specialise in?

Modern web stacks — Next.js, React, TypeScript, Node.js, and headless content systems. I have deep experience with design systems (including the NHS and GOV.UK patterns), accessibility tooling and performance engineering. For audits I’m stack-agnostic.

How do engagements typically start?

A short free call to understand the problem, a written proposal with scope, price and timeline, and a signed agreement before any work begins. Audits are fixed-price; retainers and fractional CTO work are billed monthly.

Kry / Livi — NHS GP practice websites platform

A platform that powers the public websites for NHS GP practices across the UK — accessible, fast and secure enough to carry primary-care traffic.

Client: Kry / Livi
Role: Software Developer & Scrum Master
Year: 2023
Duration: 18 months

In short

Multi-tenant public-facing websites for NHS GP practices.
Accessibility, performance and security treated as features, not afterthoughts.
Both writing the code and running the process as Scrum Master.

The brief

NHS GP practices need a public website their patients can rely on — to find contact details, check opening hours, register, and access the online services the practice offers. When the same underlying platform serves dozens of practices, any regression or accessibility failure is multiplied across every one of them.

Kry / Livi set the bar high: the platform had to be accessible, fast for patients on slow connections and older devices, and secure enough to carry NHS primary-care traffic without a second thought.

Approach

Multi-tenant platform design — one codebase, per-practice content and branding.

Performance budgets enforced in CI — regressions on Core Web Vitals blocked merges.

Accessibility audits (automated + manual) on every iteration, not just at release.

Running the team's Scrum ceremonies — standups, planning, retros — so delivery rhythm kept up with quality expectations.

What I delivered

Public-facing GP practice website platform
Accessibility remediation at WCAG 2.1 AA
Performance-budgeted CI pipeline
Scrum facilitation and process improvements
Documentation and onboarding for new engineers

Outcomes

A platform trusted to power public NHS GP practice sites across the UK
Consistent Core Web Vitals performance across practices on a range of networks and devices
Accessibility-first baseline that later feature work could be held to
