Websites and modules that actually get used
Not one-off showcase projects, but sites and platforms I build, maintain, and keep improving myself — including the infrastructure around them. Two ongoing examples below.
Eurofly / Vechtdal Paragliding
Website, booking modules & infrastructure
Marketing sites and functional modules for a paragliding school: from content management to the technology underneath. Including a fully custom-built backend for bookings, member management, and live flying-status updates — built to last for years, not to be replaced after one season.

SaaS platform: tenant app + management console
A full multi-tenant platform with a customer-facing app and a separate operator console for management, usage analytics, and tenant administration. What sets it apart: visual photo-based proposals, smart quoting suggestions, automatic invoicing, and direct export to bookkeeping — one continuous flow from proposal to invoice, instead of disconnected tools stitched together.

In-house accounting application, built to order
A custom-built accounting application that acts as a shadow ledger: instead of a stack of receipts and invoices, the system delivers the records neatly categorized, so an accountant can handle VAT filings and the year-end close quickly and efficiently.
