React Development — Context API, Hooks, Modern Stack
Looking for React developers who know Context API specifically? You’re likely dealing with an existing codebase that uses Context over Redux, or you’re making that architectural choice now and want developers who won’t reflexively reach for a heavier solution.
CimpleO builds React frontends with the right state management for the job — Context API for component-scoped and mid-complexity state, Redux Toolkit or Zustand when the data model genuinely warrants it, React Query for server state. We don’t over-engineer.
What We’ve Built
ZeroDark — HR & Task Management Platform — React (TypeScript) frontend for a shipyard operations platform. Crew scheduling, task assignment, role-based access. Phased loading with code splitting to minimise bundle size on slow connections.
Hoppn Food Delivery — React admin dashboard + React Native mobile. Complex real-time order state managed without Redux overhead.
Mertim Marketplace — React + NestJS. Multi-role marketplace with delivery logistics, payment flows, and a seller/buyer dashboard.
AppSec.Hub — Frontend for a cybersecurity platform managing SSDL pipelines — user profiles, application risk dashboards, vulnerability reporting.
Context API vs Redux — When Each Makes Sense
Clients often ask. Short answer:
- Context API + useReducer: correct for auth state, theme, feature flags, and most mid-complexity cases. Zero dependencies, easy to test.
- Redux Toolkit: worth it when you have many async slices, need time-travel debugging, or the team is already trained on it.
- Zustand / Jotai: lightweight alternative for shared state without boilerplate.
- React Query / SWR: server state doesn’t belong in Redux — these handle caching, refetching, and background sync properly.
We assess your existing architecture and work with what makes sense — not what’s fashionable.
Engagement Models
Feature team: we take ownership of a frontend area — component library, dashboard, checkout flow — and deliver it to spec.
Staff augmentation: a senior React developer joins your existing team. Useful for velocity bursts or specialist coverage.
Greenfield SPA: full product frontend from design system to deployment. We’ve done this end-to-end for ZeroDark and Mertim.

Frequently Asked Questions
How much does React development cost?
A React SPA with auth and core features: $15,000–$40,000. A complex dashboard or multi-role web application: $40,000–$100,000+. Dedicated React engineer retainer: from $7,000/month. Timeline: 6–12 weeks for focused features, 3–6 months for full applications.
Context API or Redux — which should we use?
Context API + useReducer for auth state, theme, feature flags, and most mid-complexity cases — zero dependencies, easy to test. Redux Toolkit when you have many async slices, need time-travel debugging, or the team is already trained on it. React Query or SWR for server state — it doesn't belong in Redux. We assess your architecture and work with what fits, not what's fashionable.
Next.js or Create React App — which is better?
Next.js for most new projects — SSR/SSG for SEO, file-based routing, built-in image optimisation, and a strong ecosystem. CRA/Vite for SPAs where SSR isn't needed and you want simpler deployment. We use Next.js by default unless there's a specific reason not to.
Can you join our existing React codebase?
Yes. We review existing codebases before committing — component structure, state management approach, bundle size, test coverage, and technical debt. We give you an honest assessment, not a sales pitch.
Do you write tests for React components?
Yes — React Testing Library for component tests, Jest for logic units, Cypress or Playwright for end-to-end flows. We focus on testing behaviour, not implementation details. Test infrastructure is included in every engagement.
