Web development for platforms that stay fast as they grow
Modern web applications and sites built for speed, accessibility, and search visibility — and structured so they are still maintainable after twenty releases.

- Best when
- Speed, accessibility, and search visibility matter, and the site must stay maintainable.
- Not a fit when
- A template and a page builder would genuinely do.
- First thing you get
- A performance and accessibility baseline, then the first pages built to it.
What is web development?
Web development is building websites and web applications that run in the browser, from marketing sites to full business applications. Speed, accessibility and search visibility are architectural decisions made early, not polish added before launch. We build with server rendering by default, minimal client-side JavaScript and semantic, accessible markup.
Web performance is not a polish item you address before launch. It is an architectural property: what renders on the server, how much JavaScript reaches the browser, how images are delivered, and what blocks the first paint. Decisions made in week one determine whether the site is fast in month twelve.
We build with server rendering by default, ship as little client-side JavaScript as the interface genuinely needs, and treat accessibility and semantic markup as part of the build rather than an audit afterwards. All three happen to be what search engines and AI answer engines reward.
What this includes
- 01
Web application development
Complex, stateful applications with authentication, permissions, and real data behind them.
- 02
Marketing and content sites
Fast, well-structured sites built to rank and to be edited without a developer.
- 03
Performance engineering
Core Web Vitals treated as a budget enforced in CI, not a report generated once.
- 04
Accessibility
Semantic markup, keyboard navigation, and screen-reader support built in from the start.
- 05
Design systems
A component library so the tenth page looks like the first and costs less to build.
- 06
Testing and CI
Automated checks on every change so releases stay uneventful.
Situations we see most often
Your site is slow and it is costing you
Poor performance suppresses both search ranking and conversion, and it rarely fixes itself incrementally.
You need an application, not a website
Logins, permissions, workflows, and real data — beyond what a page builder can carry.
Marketing cannot ship without engineering
Every copy change is a developer ticket, so the site stops being updated.
You are rebuilding an ageing frontend
A working backend with a frontend that is now the constraint on everything.
What to know before you start
Website or web application: which do you need?
A website mainly publishes: pages, content and forms that bring in enquiries. A web application is used: people log in, enter data, follow workflows and depend on it to do their job. Both run in a browser, but they differ in architecture, cost and how they are tested.
Many projects are a mix, such as a marketing site with a customer portal behind a login. We scope the two parts separately, because building the marketing pages like an application wastes money, and building the application like a website fails under real use.
Why does speed matter, and how is it built in?
Slow pages lose visitors before they read anything, and Google uses Core Web Vitals, its measures of loading speed, responsiveness and visual stability, as a ranking signal. Speed is decided early, by what renders on the server, how much JavaScript reaches the browser, and how images are delivered.
We render on the server by default, ship only the JavaScript the interface needs, and enforce a performance budget in CI, so a release that makes the site slower fails before it reaches users.
Which technology should your site use?
Our default is Next.js with React and TypeScript, because it serves pages fast, ranks well and scales from a content site to a full application. Content is edited through a headless CMS your team can use without calling a developer.
For a simple brochure site that rarely changes, a mainstream site builder can be the honest answer, and we will say so. The right stack is the one that fits how often the site changes and who changes it.
How do you protect search rankings during a redesign?
Rankings are attached to URLs and content, so a redesign that changes either without a plan can undo years of search visibility overnight. Before anything launches, we map every existing URL that has traffic or links to its new home and set up permanent redirects.
We also carry over titles, descriptions and structured data, check that the new pages render fully for crawlers, and monitor Search Console after launch to catch anything missed. The goal is a site that looks new to people and familiar to search engines.
What drives the cost of a website or web application?
Web projects range from a few pages to full business applications. These are the factors that move cost most.
| Factor | Effect | Why it matters |
|---|---|---|
| Website or application | High | Logins, roles, workflows and data make an application several times the work of a content site of similar size. |
| Integrations | High | CRM, payments, booking, ERP and search integrations each need design, error handling and testing. |
| Page types and templates | Medium | Cost follows the number of distinct templates, not the number of pages, since pages reuse templates. |
| Content migration | Medium | Moving and restructuring existing content, with redirects from old URLs, protects search rankings but takes real effort. |
| Custom design | Medium | A bespoke design system costs more than adapting an existing one, and pays off across a large site or product. |
| Languages | Medium | Each additional language adds content workflows, routing and SEO configuration. |
| Performance and accessibility | Low | Built in from the start, they cost little; retrofitted into a finished site, they cost a lot. |

Questions we get asked
01Will the site be good for SEO?
Server-side rendering, semantic markup, structured data, and fast load times are built in rather than added later — those are the technical foundations ranking depends on. Content and authority still do the rest of the work, and no build alone delivers rankings.
02Can our team edit content without us calling you?
Yes. We integrate a CMS where content changes frequently, so marketing can publish without a deployment. Where content is largely static, keeping it in the codebase is simpler and cheaper.
03Do you redesign existing sites?
Yes — both visual redesigns on a sound foundation and full rebuilds where the underlying platform is the actual problem. We will tell you which one you are looking at after reviewing it.
04Where will the site be hosted, and who owns it?
In your own accounts. Code, hosting and domains are set up in your name and handed over with documentation, so you can change providers or developers at any time.
05Is the site accessible?
Accessibility is part of the build, not an audit afterwards: semantic markup, keyboard navigation, readable contrast and labelled forms, checked against WCAG guidelines before release.
