React & Tailwind interfaces that make a difference
A performant application starts with an interface that works. At KERN-IT, we develop fast, accessible and maintainable React frontends: single-page applications, real-time dashboards, client portals, mapping interfaces with Leaflet and MapLibre.
Our frontend team works in tandem with our backend developers Python/Django/FastAPI to deliver cohesive full-stack applications. Design is handled in-house by our UX/UI team using Figma for prototyping.
Our frontend stack
React & Next.js
Modern React applications with TypeScript, state management, routing, SSR/SSG with Next.js. Reusable components and custom design systems.
Tailwind CSS
Our default CSS framework. Utility-first, responsive, custom design tokens. All our recent projects are styled with Tailwind for minimal and performant CSS.
Leaflet & MapLibre
Interactive maps with clustering, dynamic filters, routes, GeoJSON data. Our KERN MAP solution is built on this mapping expertise.
Dashboards & Grafana
Real-time data visualisation interfaces: charts, maps, interactive tables, monitoring. Grafana integration for operational tracking.
Types of frontend projects
Business applications
Client portals, back-offices, management interfaces. SPA architecture connected to your Django or FastAPI APIs. Complex forms, workflows, custom dashboards.
Mapping interfaces
Store locators, heritage maps, network visualisation, real-time tracking. Liberation Route Europe and Cushman & Wakefield are among our references.
Websites & CMS
Performant websites with Wagtail (headless) or WordPress. Animations, transitions, responsive design. Optimised for SEO and Core Web Vitals.

Frequently asked questions
React offers the largest ecosystem, most active community and best integration with Next.js for SSR. Combined with Tailwind CSS, it enables fast and maintainable development. The choice depends on your constraints, team and long-term maintainability.
We develop REST APIs (Django REST Framework or FastAPI) that the React frontend consumes. The architecture is decoupled: the frontend can be deployed independently from the backend. For real-time data, we use WebSocket via Socket.IO.
It's one of our specialities. We use Leaflet and MapLibre GL to create interactive maps with clustering, filters, routes and geospatial data (PostGIS). Our KERN MAP solution enables rapid deployment of custom mapping tools.
Yes. We carry out progressive migrations: from jQuery to React, from Django templates to a React SPA, from classic CSS to Tailwind, from JavaScript to TypeScript. The approach is incremental to minimise risks.
Tailwind CSS is utility-first: no predefined classes imposing a generic style. Each project has a unique design. The CSS generated in production contains only what's used, improving performance. All our recent projects are built with Tailwind.
