Web applications

Web application development

A dashboard, planning tool or internal application that works everywhere — at the office, at home and on the shop floor, with no install on every PC. I build custom web applications that grow with your organisation.

What you get

One app, reachable everywhere

A modern web application runs in the browser: no per-workstation install, always the latest version and reachable wherever you work. Ideal for teams that want to share the same overview.

ReactPython / FastAPIDatabasesREST API
  • Dashboards & overviews
    Real-time insight into your data, with charts, filters and export to Excel or PDF.
  • Internal tools & portals
    Applications your team works with — user management, roles and permissions included.
  • Links to existing systems
    The web app talks to your existing software, databases or machines through APIs.
  • Maintainable and secure
    Type-safe code, authentication and a clear architecture that lasts for years.
REAL-WORLD EXAMPLE

PlannerTool — web app as a desktop app

A complete planning and capacity tool with a React frontend, built as a web application but shipped as a single Windows install on which multiple PCs collaborate in real time.
