REACT · FRONTEND

React, built to stay maintainable.

We build React interfaces that a team can still reason about in year two: typed props, server components where they pay off, and no state-management cargo cult.

[THE SHORT VERSION]

React is the default. Discipline is the differentiator.

Almost everyone can write React. Far fewer write React that does not rot. The hard parts are data flow, render boundaries, and knowing which state belongs on the server. We treat those as design decisions, not afterthoughts.

When it fits
  • You want a rich, interactive UI with a large hiring pool behind it
  • You expect the frontend to be maintained by more than one team over time
  • You need a shared component system across web and (via React Native) mobile
When it does not
  • A mostly static marketing site, where a lighter setup ships faster
  • A throwaway internal script, where a UI framework is overkill
[HOW WE BUILD IT]

How we build with React.

01

Model the data, then the UI

We design the data flow and server/client boundary first. Components follow the data, not the other way around.

02

Typed end to end

TypeScript from the API contract to the prop. If it compiles, a whole class of runtime bugs is already gone.

03

Server-first where it pays

Server components and data fetching on the server reduce client bundle and round trips. We use client state only where interaction demands it.

04

Test the seams

Component and integration tests on the parts that break: forms, data loading, and edge states. Handoff includes the test suite.

[COMMON QUESTIONS]

Questions we get asked.

React or Next.js?
Next.js is React with routing, server rendering, and a build system already decided. For most products we reach for Next.js. Plain React (with Vite) fits when you are embedding a widget or have a non-standard rendering need.
Do you use Redux?
Rarely. Most apps need server state (handled by the data layer) and a little local state. We add a state library only when the app genuinely has complex shared client state.
Can you take over an existing React codebase?
Yes. We start with an audit of the data flow, type coverage, and render hotspots, then fix in priority order rather than rewriting for its own sake.
