React development that ships and keeps working
React is now the default choice for modern web UIs — but the difference between a React app that delights users and one that becomes a maintenance headache comes down to the decisions made before the first line of code. Architecture, state management, data-fetching strategy, testing approach, and component design — these choices compound over time.
We have been building production React applications since React was new. Our practice covers single-page applications, full-stack Next.js platforms, data-dense dashboards, admin panels, customer portals, and component libraries. Everything we ship is TypeScript-first, accessibility-compliant, tested, and built to be extended by whoever comes after us.
What We Build
Four categories of React application we have shipped repeatedly — each with a distinct set of requirements.
Dashboards
Turn data into decisions with purpose-built dashboards
We build dashboards that surface the right data at the right time — not cluttered screens full of charts nobody reads. Every dashboard we ship is fast, responsive, and designed around the specific decisions your users need to make.
What's included
- Real-time and historical data visualisation
- Multi-source data aggregation (APIs, databases, spreadsheets)
- Interactive charts, tables, maps, and KPI cards
- Drill-down views and filter/search controls
- Role-based data visibility — managers see more than staff
- PDF export and scheduled email reports
Admin Panels
Powerful internal tools for your operations team
Admin panels are where your team actually runs the business. We build them to be fast, intuitive, and comprehensive — with audit logs, bulk actions, permission systems, and the specific workflows your operations team needs.
What's included
- User management — create, edit, suspend, role assignment
- Content management and CMS-style editors
- Bulk operations with confirmation and undo
- Full audit log of every action
- Multi-role access control (RBAC)
- Search, filter, and export across every data table
Customer & Partner Portals
Self-service interfaces your customers actually use
A well-designed customer portal reduces support volume, increases retention, and makes your product feel premium. We build portals that handle everything from onboarding and account management to billing, usage analytics, and ticket submission.
What's included
- Onboarding flows with guided setup wizards
- Account management — profile, billing, team members
- Usage dashboards and subscription management
- Document upload, download, and e-signature flows
- Support ticket submission and status tracking
- White-label options for partner-facing portals
Custom UI Component Libraries
Design systems that scale across your entire product
Ad-hoc styling decisions accumulate into inconsistency. We build component libraries that encode your brand — typography, colour, spacing, interaction patterns — into reusable, fully typed, accessible React components that every team member can use confidently.
What's included
- Fully typed TypeScript component APIs
- Storybook documentation with interactive examples
- Design token system for consistent colour, spacing, and type
- Dark mode and theme switching support
- WCAG 2.1 AA accessibility compliance
- Published as a private npm package for your team
Built to a Higher Standard
These are not optional extras — they are how we build every React application we ship.
TypeScript throughout
No any shortcuts. Full end-to-end type safety means fewer runtime bugs and a codebase that is safe to extend.
Core Web Vitals optimised
Code splitting, lazy loading, image optimisation, and server components — your app loads fast and stays fast.
Fully responsive
Every interface works on mobile, tablet, and desktop — not an afterthought, designed for all viewports from the start.
Accessibility (WCAG 2.1 AA)
Keyboard navigation, screen reader support, focus management, and colour contrast — inclusive by default.
Test coverage included
Unit, integration, and end-to-end tests shipped with every project. You get a codebase you can refactor with confidence.
SEO & Open Graph ready
Structured data, canonical URLs, Open Graph tags, and sitemap generation — built in for every public-facing page.
Clean, documented code
We write for the next developer. Clear naming, consistent patterns, and inline documentation for complex logic.
Design system included
Colour tokens, spacing scale, typography system, and a component library so every new feature looks consistent.
Technologies We Use
Proven, modern tools — chosen per-project for performance, developer experience, and long-term maintainability.
How a React Project Works
A disciplined delivery process — from discovery to a production deployment your team can maintain.
Discovery & Requirements
We start by understanding your users, your data, and your constraints. Who uses this application and what decisions do they make with it? What back-end systems does it need to connect to? What does success look like six months after launch? We document everything before proposing a solution.
Architecture & Design Proposal
We produce a technical specification — routing structure, state management strategy, API contract, data-fetching approach, component hierarchy, and deployment plan. You receive a fixed-price quote alongside the spec so you know what you are committing to.
Component Design System
Before writing application code, we establish the design system — typography, colour tokens, spacing scale, and the core component library. This foundation means every screen that follows is consistent and every new feature has reusable building blocks to draw on.
Iterative Sprint Build
Development runs in two-week sprints. At the end of each sprint you receive a deployed staging link with working features to review and test. Feedback is incorporated into the next sprint — you shape the product as it is being built rather than at the end.
Testing & Performance Audit
Before any production release, every screen goes through our QA checklist — functional testing, cross-browser and device testing, accessibility audit (WCAG 2.1 AA), Lighthouse performance run, and a security review. We fix anything below our quality bar before you see it.
Deployment & Handover
We manage the production deployment — CI/CD pipeline, environment configuration, monitoring setup, and DNS. You receive full source code, infrastructure documentation, a component library guide, and a handover session with your team.
