ROVQIX builds React applications in TypeScript — dashboards, internal tools, customer portals and design systems. We handle component architecture, state management, rendering performance and accessibility, and hand over a codebase your team can extend without rewriting.
Most React problems we are called in to fix are structural: state in the wrong place, a context re-rendering the world, or a component with nineteen boolean props. We build to avoid that from the start.
Strict, end to end
Accessibility target
Not one-off components
Critical paths covered
Composition over configuration, a clear split between UI primitives and product components, and folders organised by feature.
Server data in a cache, view state in the URL, UI state local — not everything in one global store.
Profiled, not guessed: state placed correctly, contexts split, long lists virtualised, interactions under budget.
Semantic elements, keyboard operation, focus management and screen-reader testing on the primary flows.
A documented set of primitives with tokens, variants and usage guidance so future features look consistent.
Unit tests for logic, Testing Library for interaction, and a handful of reliable end-to-end tests on revenue paths.
When the entire application sits behind a login and no page needs to be indexed or fast on a cold first load.
Internal tools, heavily interactive editors and embedded widgets are legitimate cases for a Vite-based React SPA. It has a smaller conceptual surface, which matters for a small team maintaining it long term.
If any part of the product is public — marketing pages, a pricing page, documentation, shared links — we recommend Next.js so that content is server-rendered and indexable. We will tell you which side of that line your project falls on during scoping.
Next.js is React with routing, rendering and build decisions already made. We use Next.js for anything with public pages and plain React for applications entirely behind authentication.
Yes — that is a common engagement. We profile first and give you a prioritised list with expected impact before doing any work, so you can decide how far to go.
It depends on the state. Server data goes in a query cache or server components, shareable view state goes in the URL, and genuinely global client state goes in a small store. We avoid putting everything in one place.
Yes, focused where they pay off: business logic, interactive components and a small set of end-to-end tests covering the flows that generate revenue. We do not chase coverage percentages.
Indicative ranges in USD. Every engagement is quoted to a written scope before work starts, so the number you approve is the number you pay.

How we think about this work, in more depth.
React development
A 30-minute call, then a written proposal with scope, price and timeline within two to three working days. No retainer required to get a real number, and no obligation if the answer is that we are not the right fit.
