Why RPMStack for React Development

Three principles we don't compromise on.

01

Senior-only engineers

Every line of React is written by engineers with 8+ years of production experience — no juniors, no offshore handoffs.

02

Component-first architecture

We ship design systems, not one-off screens. Storybook, TypeScript strict mode, and testable primitives from the start.

03

Performance as default

Bundle-size budgets, code-splitting, and lazy-loading baked in — not bolted on before launch.

FAQ

Common questions.

Do you work with existing React codebases?

+

Yes — a large share of our work is either extending or refactoring existing React apps. We start with a codebase audit and give you an honest assessment of what to keep, refactor, or rewrite.

How long does a typical React build take?

+

A focused marketing site or component library ships in 4–6 weeks. Complex dashboards and multi-tenant apps typically run 10–16 weeks. Every project gets a fixed timeline in the written proposal.

Which state management do you use?

+

It depends on the shape of the app. We default to TanStack Query for server state and Zustand for local state — but we're comfortable with Redux Toolkit, Jotai, and Context-only where those fit better.

Do you handle testing and CI?

+

Yes. Every project ships with Vitest unit tests, Playwright E2E coverage for critical flows, and a GitHub Actions pipeline that runs the full suite on every PR.
