Build
- 3D & Product Visualisation
  Renders no one can tell from a photograph, built from your CAD before a single unit exists. Take the orders, test the market, and let the product follow the demand instead of gambling ahead of it.
  Web Development
  Anyone can ship a template. We engineer fast, secure, standards-correct builds with zero console errors, structured so the next person can actually maintain them.
  UX & Conversion Rate Optimisation
  Your best customers leave at the checkout, and not one of them tells you why. We find the friction with evidence rather than opinion, and fix the points where the money slips out.
  Website Design
  Pretty doesn't pay. Conversion does. We design for the person actually trying to buy from you, not an awards panel, so clarity and speed do the selling.
  Is Your Website Bleeding Revenue?

Systems
- Page Speed & Performance Engineering
  A slow site loses customers before the page finishes loading, and none tell you on the way out. We tune every layer until yours hits the rare intersection of sub-30ms TTFB, A+ security, and 99+ PageSpeed scores, because fast pages sell more.
  Website Care Plans
  Neglecting updates and security is a risk paid for in costly downtime. Our proactive website maintenance services handle your hosting, patching, and threat mitigation so you never have to worry about your site falling over.
  CRM & Automation
  The chasing, copying and re-keying that eats your team's day is work a system should be doing. We build CRMs and automation that joins your data up and hands those hours back.
  Platform Migrations
  Most businesses run on systems that grew by accident, bolted together over years until nobody owns the whole. We move you onto something coherent, without the wheels coming off the business while we do it.
  Manual work bogging you down? Slow website?
  Accelerate your business
Secure
- Cyber Essentials
  The certificate a contract, a tender or an insurer suddenly demands, usually the week you cannot invoice without it. We pass it solo, on the deadline that is actually breathing down your neck.
  ISO 27001
  ISO 27001 has a reputation for eating a year and a department. Most of that year is meetings. We build a system that fits how you actually run, get you audit-ready, and leave the theatre out of it.
  PCI DSS
  If money moves through your checkout, this is not optional. We scope the right SAQ and fix what fails it, so you stay compliant without re-architecting what already works.
  Emergency & Incident Response
  Under active attack, the clock is the enemy and a plugin will not save you. We step in fast, stop the bleeding, lock the network down, and harden it so the same door does not open twice.
  Are you under active attack?
  Get emergency help
Grow
- AI and Search Visibility
  Your buyers now ask ChatGPT, Gemini and Claude before they ever Google you. We build the authority and structure that gets you named in those answers, instead of buried under the old blue links.
  Technical SEO
  Search engines read a different version of your site, the one under the design, often broken in ways no visitor sees. We find what the crawler sees and fix it, so the work you have already paid for can finally rank.
  International SEO
  Machine translation writes fluent text no local would ever type into a search box. We handle hreflang and architecture properly, backed by years of winning business in German, French and Spanish, not a translation plugin.
  Content Strategy
  Anyone can publish endlessly now, which is exactly why volume stopped working. We plan what is genuinely worth writing, for whom and why, so the words pull in buyers instead of filling a calendar.

Reading Progress & Table of Contents Plugin: Now Live on WordPress.org

When I build software for clients, it’s usually solving a very specific problem. Every so often, though, Reading Progress & Table of Contents Plugin: Now Live on WordPress.org

A super simple thing I’ve built is now officially out in the wild. Just a handy little plugin, made properly and designed to help UX and indexability.

Erryn Reading Progress & Table of Contents is live in the WordPress plugin directory.

The idea started from something simple: long-form content is much easier to navigate when people can see where they are, what comes next, and how much is left, this is especially important on a mobile device in a long piece of content or a product page. Now plenty of plugins already handle one part of that, but I wanted something that combined reading progress and navigation without turning a straightforward job into another miniature software platform.

The plugin automatically builds a table of contents from the headings on a page or post, tracks reading progress as somebody scrolls and highlights the section they’re currently reading.

The critical thing about this plugin is that it will be actively supported, there’s no “upgrade to premium” nonsense, plus, coming from a cyber security and optimisation background, it’s been built to be featherweight and secure on your website, with structured data and WCAG contrast checker built in (I’m all about speed, ranking and compliance).

There are two main layouts: a horizontal reading progress bar and an expandable side rail. Both are designed to stay out of the way until they’re useful, with automatic responsive touch behaviour for smaller screens and mobile devices.

It also includes:

Automatic heading detection from H2 to H6
ItemList structured data
Rank Math, Yoast, AIOSEO table of contents recognition
WPML, Polylang and right-to-left language support
WCAG contrast checker
Manual anchor support where more control is needed
Horizontal progress bar and side-rail layouts
Current-section highlighting while scrolling
Automatic light and dark mode support
Theme-aware colours with custom colour options
Per-post controls

There is no jQuery dependency, no frontend framework, no external tracking and no random API calls disappearing off somewhere to contemplate their purpose in life, track you or slow down your website. The plugin does the job locally and leaves the rest of the page alone.

For most sites, setup is deliberately uneventful. Install it, activate it and it should detect the content structure automatically. The additional settings are there for sites with fixed headers, unusual templates or more particular styling requirements, rather than because everybody should need seventeen switches before a progress bar can move from left to right.

This plugin is pretty basic but will be expanded on with extra features and layouts in-between more involved projects.

It is free and available now from the official WordPress plugin directory.
