React Development
We build React applications that are typed, tested, and architected to stay maintainable as they grow. React is a tool with a wide surface area; the decisions that matter are not which library to install but how state flows, how components are structured, and where the boundary between client and server sits.
Capabilities
What we build with React
Full applications
Production Web Applications
Complete React applications with routing, authentication, API integration, and state management. Architecture decisions made upfront about where data lives, how it flows, and how components are organized before the first component is written.
Reusable UI
Component Libraries and Design Systems
Shared component libraries with Storybook documentation, TypeScript prop types, and consistent behavior across all design states. Built to be consumed by multiple product teams without breaking changes.
Tables · Charts · Filters
Data-Heavy Dashboards
React interfaces for displaying and interacting with large datasets: sortable and filterable tables, charting integrations, and export functionality. Server-side pagination and filtering for datasets that cannot fit in the browser.
Class → Hooks · Legacy → Modern
React Migration
Migrating class components to function components with hooks, updating React Router from v5 to v6, moving from Redux to lighter state management, and updating build tooling from Create React App to Vite.
Rendering · Bundle size
Performance Optimization
Diagnosing React performance problems with the React DevTools Profiler: unnecessary re-renders, missing memoization, large component trees, and bundle splitting. We fix the problem, not the symptom.
Unit · Integration · E2E
Testing Infrastructure
Setting up a testing stack that actually works: component tests with Vitest and Testing Library, end-to-end tests with Playwright, and a CI pipeline that runs the full suite on every pull request.
Our approach
State management is an architectural decision
React gives you multiple ways to manage state, and the right choice depends on what the state represents. Server state belongs in React Query or SWR, not useState. Global client state belongs in Zustand or similar, not a context that re-renders everything. We make these decisions at the start of a project, not after performance problems appear.
Components should do one thing
A React component that fetches data, manages multiple pieces of state, handles errors, and renders complex UI is a component that is hard to test and hard to change. We decompose components into focused units and colocate state as close to where it is used as possible.
TypeScript prop types are not optional
React components without TypeScript are a maintenance problem. We type all component props, including event handlers and render props, from the start. This is not a pedantic preference — it is what makes a component library usable by a team over time.
The browser is the production environment
Performance matters in real browsers on real devices, not just in development mode on a fast laptop. We test with Lighthouse, use the Network tab to validate load behavior, and address Core Web Vitals before they become a user complaint.
