Financieel Plan — for Zorg voor Vermogen
Financieel Plan is a financial-planning webapp built for Zorg voor Vermogen, Evert Boon’s developer of financial insight tools. The project pairs a calculation engine that stays independent of the interface with delivery as both a browser-based web app and a bundled native app.
- Situation
- Zorg voor Vermogen had built a prototype calculation tool themselves and wanted a future-proof version built.
- Role
- Product architecture, calculation engine, and delivery as a bundled web and native app.
- Key decision
- Financial calculations stay outside the interface, in a versioned, independently tested package.
- Current outcome
- Client project in progress; final results follow after delivery.
Situation and goal
Zorg voor Vermogen had built its own prototype of a financial-planning calculation tool and wanted a future-proof version built for use with clients.
The webapp needed to run locally in the browser without a required backend, and later travel into a native app shell without rebuilding the underlying logic.
Decisions and implementation
The financial calculations live in their own package, with no dependency on the interface, storage, or platform. A versioned plan schema and domain package sit between the calculations and the app, so plan data stays validated and portable.
The same webapp is bundled into an Expo WebView host, so the calculation engine and interface are built once and reused for both the browser and the native app.
Current status and reflection
The project is in progress. Each slice of functionality is recorded as an architecture decision and checked against the calculation and domain registers before it lands.
No client quote, results, or performance figures are claimed here; those can only be added after delivery and approval.
