Hire a freelance React developer

I build React applications that look good and hold up in production: dashboards, ecommerce tools, admin panels, and full products. I have been working with React since the early days of the ecosystem, and it is still my frontend tool of choice.

What makes my work a bit different is that I also design. Most of the interfaces in my portfolio were designed and built by me, so you do not need a separate designer to get a UI that feels considered.

Sabine Staggl Founder, Noisli

We fully enjoyed working with Ruan!

He is very communicative and proactive, often bringing in his own ideas and he doesn’t shy away from going the extra mile.

What I can help with

  • Building React applications from scratch with TypeScript
  • Complex dashboards, tables, and data heavy interfaces
  • Design systems and reusable component libraries
  • Data fetching and caching with TanStack Query
  • User interface design and prototyping
  • Performance work: bundle size, rendering, and perceived speed

Experience

The VESYL app, where I was founding engineer for close to five years, is a large React application: order management, shipping workflows, integrations, and settings, all designed and built with care. I have shipped similar frontend work for Queie, Flipfox, BasisBoard, and Frevo.

You can see screenshots of this work on my work page, and read my writing on React patterns like typed API clients with TanStack Query and OpenAPI.

Questions

Do you design the interfaces as well as build them?

Yes. I am not a designer by trade, but I have designed and shipped polished interfaces for most of my clients. If you already have a designer, I am happy to work from their files. If you do not, I can take the product from rough idea to finished UI.

Do you work with Next.js and other React frameworks?

Yes. I pick the framework based on the project: Next.js, Remix, Vite with React Router, or Astro with React islands for content heavy sites. If you already have a stack, I work with what you have.

Can you improve an existing React app instead of starting over?

Yes, and most of the time that is the right call. I can audit an existing app, fix performance and UX problems, and modernize it incrementally instead of rewriting from scratch.

How much does it cost to hire a freelance React developer?

The cost depends on the scope of the work. I quote fixed project fees or monthly retainers, never hourly rates, so there are no surprises. Email [email protected] with what you have in mind and I will send a proposal.
