Should my project be React or Next.js?

If it's an app behind a login with little need for SEO, plain React (Vite) is lean and fast. If pages need to rank or render on the server, I build it with Next.js instead.

Can you fix a slow, laggy React app?

Yes — I profile renders with the React DevTools, add memoization and code-splitting, and remove unnecessary state updates. Most 'slow React' problems are re-render and bundle issues, both fixable.

Do you build reusable component libraries and design systems?

Yes. I build typed, accessible component libraries (often on Radix + Tailwind) with documentation so multiple apps share one source of truth.

Can you migrate class components to hooks?

Yes, incrementally — converting class components to function components and hooks without freezing feature work.

Are you a React JS development company or a freelancer?

An independent React developer. You work with me directly, with one person responsible for component planning, API integration, testing, and performance review.

React development creates browser-based interfaces such as dashboards, internal tools, and single-page applications using reusable components. It is intended for teams that need a new React interface, a component system, a legacy frontend migration, or performance work on an existing application.

What I build

What is included in React development?

SPAs & dashboards

Data-heavy single-page apps with client-side routing, charts, and TanStack Query for server state and caching.

Design systems & component libraries

Accessible, reusable components (Radix primitives + Tailwind) so a growing product stays visually consistent.

Performance work

Code-splitting, memoization, and render profiling to fix janky, over-re-rendering React apps and keep Core Web Vitals green.

Migration & modernization

Class components to hooks, Webpack to Vite, and legacy jQuery/AngularJS screens rebuilt in modern React.

Problems this solves

What problems can React development solve?

A React app that re-renders the whole tree on every keystroke and feels sluggish.
UI that drifts out of consistency because there's no shared component library.
An old class-component codebase nobody wants to touch.
A bundle so large the first paint takes seconds on mobile.

Example use cases

What does React development look like in practice?

Analytics dashboard

Built a React + TanStack Query dashboard with virtualized tables and Recharts that stayed smooth over thousands of live rows.

Shared component library

Extracted a company's buttons, forms, and modals into a typed, documented library used across three internal apps.

Performance rescue

Cut a marketing app's bundle by half with code-splitting and lazy routes, moving LCP from 4.1s to under 2s.

Process

How does React development work?

Plan components

Turn designs into a component tree and decide where state and data live.

Build the UI

Typed, reusable components with routing and data fetching.

Integrate & test

Connect APIs, add tests, verify on devices.

Optimize & ship

Profile renders, trim the bundle, deploy.

React is the front-end layer of my broader full stack development work. When a project needs SEO, server rendering, or file-based routing out of the box, I build it with Next.js on top of React instead.

Related services

Next.js Development Services

Next.js development uses React with server rendering, static generation, route handlers, and the App Router to build websites and web applications. It is intended for teams whose product needs search-visible pages, server-rendered content, integrated backend logic, or content managed through a CMS.

Node.js Development Services

Node.js development provides the server-side APIs, real-time services, background jobs, and database access used by web and SaaS products. It is intended for teams building a new backend or improving an existing service that needs clearer architecture, authentication, queues, or live updates.

Full-Stack Development Services

Full-stack development covers the frontend, backend, database, authentication, integrations, and deployment of a web product. It is intended for teams that want one developer to own these connected layers or complete an existing application end to end.
