Enterprise React and Next.js application development
Geosterling Systems builds React and Next.js applications for organisations whose web platform is a core business system rather than a brochure: client portals, internal tools, trading and booking interfaces, and high-traffic public products. We work in TypeScript, with server rendering where it helps search and speed, and with architecture that a larger team can keep extending.
The work suits CTOs and engineering leads in Riyadh, the wider Gulf and London who need a senior delivery partner for a rebuild or a new platform. Arabic and English are treated as equal citizens from the first component, including right-to-left layout, so the product does not need retrofitting later.
What you get
A production Next.js and TypeScript application with a documented component library.
Single sign-on and role-based access integrated with your identity provider where required.
Bilingual Arabic and English interfaces with correct RTL layout and locale-aware formatting.
Automated tests, a CI/CD pipeline and a monitored production deployment.
Complete source code handover, architecture notes and post-launch support.
When you need this
- A legacy client or partner portal that has become slow, hard to change and difficult to pass a security review.
- A new customer-facing platform that has to serve Arabic and English audiences with the same quality of experience.
- A front end that must sit on top of existing ERP, CRM or core banking APIs without replacing them.
- An internal operations dashboard that teams rely on all day and that cannot afford instability at peak load.
How we work
Discovery and architecture
We map users, integrations, data sensitivity and load expectations, then agree the architecture, rendering strategy and hosting approach before writing product code.
Design system and foundations
A shared component library, typing conventions and the authentication layer are built first, so every later screen is faster to deliver and consistent.
Iterative build
Features ship in short cycles with working builds for your team to review, including Arabic and English states and accessibility checks at each step.
Hardening and launch
Performance profiling, security review, load testing and a staged release, followed by a handover session with your engineers.
Frequently asked questions
What drives the cost of an enterprise React application?
Scope is shaped mainly by the number of integrations, the complexity of roles and permissions, and whether the product is bilingual with full RTL support. We quote after a discovery call, once those factors are clear.
Can you rebuild our existing portal without disrupting users?
Yes. We usually migrate in stages, running the new application alongside the old one and moving journeys across once each has been verified. The timeline depends on scope, and we confirm it after the discovery call.
Why React and Next.js rather than a packaged platform?
A custom React application gives you control over performance, security posture and integrations that packaged tools tend to constrain. You also own the source code, which we hand over, so you are not tied to us or to a vendor licence.
