We build React interfaces for operational tools, business platforms and customer portals. Reusable components and deliberate state management help people find records, understand information and complete their work. An engagement can cover a new application or one complete workflow on an existing backend, with accessibility, performance and handover included in the scope.
React supports interfaces where people search, select, edit and review information. We build operational tools and portals around those tasks, using shared fields, record panels and navigation where the behavior is genuinely shared.
A React interface can work with .NET, Node.js or another documented backend. We assess the existing services and contracts before deciding what belongs in the interface and what remains in the application.
Explore two backend combinations and the tools around the interface.
C# services
A React interface can sit alongside an existing .NET application, using its APIs and established business rules.
JavaScript / TypeScript services
React and Node.js can share a language while keeping browser interactions and server responsibilities separate.
Interface components
Types across components and contracts
Development and production builds
Routes and navigation
Fetching and synchronising server data
Presentation and reusable controls
Tests around user interactions
Illustrative tool choices, selected around the application. These are complementary roles, not a required bundle; a framework may provide several of them.
The list and detail view below share one selected-record identifier. Choosing a record updates both components: the list highlights it and the detail view shows its information. React owns this interface selection; application services retain business records, permissions and validation.
Choose a sample record to update both views.
Illustrative example. Sample records. Selection makes no business changes.
The order customer has no corresponding finance account. Review the source customer and select the agreed destination account before retrying the handoff.
Review the customer mapping
Search, filters and status labels help people find the right record. Opening or editing it should preserve that context. On smaller screens, a concise record list can replace a table while retaining the information needed for the task.
When data refreshes, keep the selection and identify unconfirmed values. If refresh fails, explain the limitation and offer a retry; retained data must not appear newly confirmed.
Pagination, server-side filtering and virtualised rendering address different bottlenecks. We measure queries, requests, script cost and rendering with realistic datasets before choosing an approach.
Required fields, formats and dependent inputs need guidance before submission. Show corrections beside the relevant field, and handle loading, rejection and permission changes as part of the complete task.
Application services enforce permissions and business rules. A disabled button does not protect an API. Draft storage follows the task and data sensitivity, with clear recovery and a visible distinction between a draft and a completed action.
Keyboard access covers selection, editing, error recovery and returning to the right place. Clear labels, focus order and meaningful announcements make the whole workflow usable; a smooth sample alone does not establish production performance.
An existing application can retain its backend while one workflow receives a React interface. We first assess authentication, available contracts and rules embedded in the old screens, then release the complete task with loading, empty, error and permission states.
Adoption helps refine terminology and navigation before the next workflow changes. Handover includes reusable components, interface conventions, API assumptions and interaction tests so your team can extend the application.
