Websites that hold up
on a bad connection,
on a real phone.
We build production web applications with Next.js and React — fast because the architecture is right, not because a plugin was installed at the end.

Most sites are slow because of decisions, not code
A site gets slow when nobody owned the rendering strategy, the image pipeline or the third-party scripts. None of those are hard problems — they are simply decisions that were never made, and they compound.
We make them explicitly, write them down, and enforce them in the build. That is the whole trick, and it is why the second year of a Virtus site is not slower than the first.
Senior engineers own the outcome end to end. Nothing is handed to a black box.
Four decisions that separate a site that launches from one that performs
Rendering chosen per route, not per project
Marketing pages ship static. Content regenerates incrementally. Personalised views render on the server. One site, three strategies, because a single answer is always wrong somewhere.
A performance budget with teeth
We agree a number for time-to-interactive on a mid-range Android on a slow connection, then fail the build when a change breaks it. Budgets that only live in a document get exceeded quietly.
A CMS your editors don't resent
The content model is designed around how your team actually writes, so a banner change takes ten minutes and no engineering ticket. Most CMS failures are modelling failures, not tooling failures.
Accessibility as a build step
Keyboard flows, contrast, focus order and motion preferences are checked automatically on every pull request, and audited by hand before launch. WCAG AA is the floor, not the goal.
Twelve weeks, and you see working software every fortnight
- Weeks 1–2
Model the content and the journeys
Before design, we settle the content model and the two journeys that carry the commercial weight.
- Weeks 3–6
Design system, then pages
Components first so every later page is cheap. The system is built in code, not only in Figma.
- Weeks 7–10
Build against budgets
Iterative previews on every branch, with performance and accessibility gates running continuously.
- Weeks 11–12
Launch and hand over
SEO validation, observability, a recorded handover, and your repository with full history.
