Custom websites
For companies whose content, user journeys, or design don't fit into a rigid theme. Architecture, components, and CMS connection are shaped around the actual task.

If you want to have a website programmed, you need technology that fits the task. NJUME builds custom websites and web apps with React, Next.js, Vercel, and documented APIs when Shopify, WordPress, or site builders aren't enough.
Next.js & React
Modern frontends are built with performance, maintainability, SEO, and clear responsibilities in mind — not because a framework happens to be popular.
Portals & logins
Client areas, documents, tasks, status views, and custom roles can be bundled in protected portals. Privacy and access control are planned in from the start.
API integrations
Inventory systems, product data, booking tools, CRM, payments, or internal services are connected through documented interfaces. Error cases and operations are part of the planning.
AI & LLM integrations
OpenAI, ChatGPT, Claude, or other models can be integrated into websites, portals, and internal tools via APIs. Permissions, data, costs, and human approvals are planned to fit the use case.
Vercel, domains & hosting
Deployment, domain connection, DNS, SSL, and environment variables are set up to suit the architecture. Depending on the project, we work with Vercel, Hostinger, or another suitable hosting solution. The comparison Vercel or traditional hosting explains the differences.
Automations
Recurring workflows between website, email, database, and internal systems can be automated in a targeted way once the benefit and control points are clear. This also includes AI automation and n8n integration with API, CRM, or ERP connections.
Performance & quality
Semantic HTML, responsive implementation, accessibility, secure data flows, and measurable load times are part of the development, not a repair list for later.
Technology follows the business problem.
Understand
Clarify users, processes, data, systems, and the actual bottleneck.
Architecture
Define technology, interfaces, responsibilities, and risks.
Development
Build in sensible stages, integrate, and test in staging.
Operations
Publish, document, monitor, and develop further in a targeted way.
How much does it cost to have a website programmed?
The effort depends on user journeys, data model, integrations, roles, design, and any existing codebase. The article What does custom web development cost? shows the key factors. After a technical assessment, the scope is translated into concrete work packages.
When is a CMS not enough?
A CMS is often perfectly sufficient. Custom development pays off when core workflows would otherwise only work with many dependencies, workarounds, or permanent manual steps.
Next.js and React?
Yes. NJUME uses Next.js, React, and TypeScript when they suit the rendering, interactivity, integrations, and later operation.
APIs and inventory systems?
Existing interfaces can be connected. We review documentation, authentication, limits, data quality, and error handling before committing to a scope.
Does NJUME take care of domain and hosting?
Yes. We can technically set up the domain, DNS, SSL, a Vercel deployment, or suitable hosting such as Hostinger. Providers and responsibilities are clearly documented before launch.
Existing codebase?
Yes. A technical assessment shows which parts are solid and where step-by-step modernization or a relaunch makes more sense.
Shopify or WordPress?
If a standard platform fits, we use it. We offer dedicated services as a Shopify agency and WordPress agency.
How are security and privacy handled?
Only the data that is needed gets processed. Authentication, permissions, external services, storage, and deletion paths are planned according to the risk.
