We use React, Next.js and TypeScript for responsive, accessible and SEO-friendly frontends. Backends in Node.js, .NET or Python. We plug into your ERP, CRM and auth. You get web apps that perform well and stay maintainable.
We build web applications that are fast, accessible and easy to maintain. Our default stack is React and Next.js with TypeScript – so you get server-side rendering for SEO, a great developer experience and a codebase that scales. Backends are in Node.js, .NET or Python depending on your existing systems and preferences. We integrate with your ERP, CRM and identity provider so users sign in once and data flows automatically. Performance and accessibility are built in from the start, not added later.
Whether you need a customer portal, an internal tool or a public-facing web app – we deliver with clear architecture, tests and documentation. After go-live we offer maintenance, new features and handover to your team if you prefer. We build for the long term: clean code, automated tests and documented APIs so your web application stays maintainable and can grow with your business. Responsive design and accessibility are standard so all users can use your app on any device; SEO is built in where the project is public-facing.
