Web Applications
Web applications that stay fast as they grow.
Customer-facing web applications and platforms engineered for speed, accessibility and search visibility — and built so they stay that way after launch.
The problem
Fast on launch day is not the same as fast.
Performance is not a phase at the end of a project. It is an outcome of architecture decisions made in the first week — what renders on the server, what ships to the browser, and how much of the page depends on JavaScript arriving before anything is readable.
Sites that were quick at launch get slower with every marketing tag, hero video and third-party widget added afterwards, because nothing in the process pushes back.
How we solve it
Performance and accessibility as build constraints.
We render on the server by default and send the browser only the JavaScript an interaction genuinely requires. Most pages stay useful before a single client component has hydrated.
Performance budgets and accessibility checks run in the pipeline, so a regression fails the build instead of quietly shipping.
03What is included
Capabilities in this service.
- Custom design and front-end engineering
- Server-rendered architecture with minimal client JavaScript
- Core Web Vitals budgets enforced in CI
- WCAG 2.2 AA accessibility, keyboard and screen-reader tested
- Structured data, metadata and technical SEO

What good looks like
- Content readable before JavaScript finishes loading
- Green Core Web Vitals on real mobile hardware, not just in a lab
- Editors who can publish without opening a ticket
These are the standards we hold the work to — not results claimed on someone else's behalf.

07Questions
Before you ask.
No. Design and front-end are built for the project. We do reuse our own engineering foundations — component patterns, CI configuration, accessibility tooling — because rebuilding those from scratch each time would cost you money for no benefit.
A focused marketing platform is typically six to ten weeks. An application with accounts, permissions and integrations is usually three to five months. We give a stage-by-stage timeline before anyone commits.
Yes. Content models are designed around what your team actually publishes, and we include training and documentation at handover.
Often. If you already have a design system we will build to it and extend it properly rather than working around it.
Pages are server-rendered, so crawlers get complete HTML. Metadata, canonicals, sitemaps and structured data are part of the build rather than a plugin added later.
