Web Application Development.
Snappy, accessible web apps that scale.
Web apps built to agreed performance budgets and accessibility criteria, and boring on the on-call rota.
About Web Application Development
The best web app is one your users don't notice. That's harder than it sounds.
Web Application Development is our default surface for most builds. We deliver complex single-page and hybrid apps with performance and accessibility priced into the design, not audited at the end.
Performance budgets, monitoring and accessibility checks can be included in the scope. We define the target devices, critical journeys and manual review needed to evaluate the delivered application.
The stack is chosen for maintainability and your ability to hire engineers who know it. The output is boring to operate, which is the goal.

Service questions
Web Application Development: common questions.
What framework do you use?
Whichever fits, React by default, Vue or Svelte when the team leans that way. We pick for hiring pool and maintainability, not novelty.
How do you handle SEO?
Server-rendered or statically generated where SEO matters. Client-only for the app surface behind auth. Same repo, same team.
Can this scale to millions of users?
The web layer scales trivially with caching and edge compute. The interesting scaling work is in the backend and database. See our Enterprise Software service for what that looks like.
