Hire a Developer / Web & App Development

Every React app looks fine — until you try to change it.

Props drilled six levels deep. State scattered across a dozen components. A simple feature request that touches everything. For 10+ years we've placed engineers with 70+ businesses, including React developers who architect components and state to stay maintainable as your app grows.

Sound Familiar?

React is easy to start and easy to make a mess of.

These are the problems teams hit as a React app grows.

A small UI change requires touching five unrelated components.

The app re-renders constantly and no one knows exactly why.

Onboarding a new engineer to the codebase takes weeks, not days.

State lives in a dozen places, and no one's sure which is the source of truth.

Testing is an afterthought, so every release is a little nerve-wracking.

Feature velocity has slowed down as the codebase has grown.

React rewards good architecture and punishes bad architecture slowly, until it doesn't. We place engineers who design components and state to stay clean as the app scales.

Who This Is For

Built for teams whose React app is growing up.

If velocity is slowing as the codebase grows, this is for you.

Startups scaling their product

The MVP shipped fast; now it needs to support real growth without breaking.

Teams inheriting a messy codebase

A previous team left behind tangled state and inconsistent patterns.

Teams needing extra React capacity

Your roadmap needs more frontend hands than your current team has.

How We Fix It

Architecture that scales with you.

Each problem above maps to how we build. Here's how we fix it.

Fixes: one change touches everything

Composable Components

Clear boundaries so a change stays contained to what it should touch.

Fixes: mystery re-renders

Deliberate State Design

State lives where it belongs, with re-renders that are predictable and profiled.

Fixes: slow onboarding

Readable, Documented Code

Consistent patterns a new engineer can actually follow quickly.

Fixes: state scattered everywhere

Single Source of Truth

One clear pattern for state, whether it's Context, Redux, or React Query.

Fixes: nerve-wracking releases

Testing Built In

Component and integration tests written as part of the work, not skipped.

Fixes: velocity slowing down

Incremental Refactoring

We improve the codebase alongside new features, not as a separate project.

Why CrecenTech

We write React we'd want to inherit.

We build and maintain our own React products, so we know exactly what a codebase looks like six months after a shortcut was taken. For 10+ years and 70+ clients, we place engineers who write for the person maintaining it next, not just for today's deadline.

Before You Ask

Questions we hear a lot.

Our app is slow and hard to change — is that a React problem?+

Usually it's an architecture problem, not React itself. Unmanaged re-renders and tangled state are common symptoms of components that grew without a plan.

Do you work with our existing state management library?+

Yes — Redux, Zustand, Context, React Query, whatever you already use. We fit into your existing patterns rather than forcing a rewrite.

Can you refactor an existing messy codebase?+

Yes, this is common work — we assess the codebase, prioritize the highest-impact refactors, and improve incrementally alongside new feature work.

How fast can someone start?+

We match from an existing vetted pool, so you're typically interviewing within days and can have someone contributing to your codebase shortly after.

Contract or contract-to-hire?+

Both. Many clients start on contract to prove fit on real work, then convert strong performers to permanent.

Get a React codebase that's a pleasure to work in.
