A donation platform with real money flowing through it
A donation platform that looks simple on the outside but has to be correct to the cent inside. Built demonstrably secure and compliant in .NET on Azure, with payments via certified providers.

Simple on the outside, but real money flows through it. Payments have to be correct to the cent, donor data is privacy-sensitive and strict rules apply around payment processing, data protection and accountability. It had to be demonstrably secure and compliant, not just working.

- 1
Architecture in clear layers: presentation, logic, domain and data separated.
- 2
Payments via PCI-DSS certified providers; never storing card data ourselves.
- 3
Security and privacy by design: encryption, access rights, audit logging and GDPR.
- 4
Reliable and traceable: idempotent processing, reconciliation and full logging.
A donation platform that is demonstrably secure and compliant: donations arrive reliably, sensitive data is protected and every euro is accountable.
