Case study
The expensive platform we didn't buy
An architecture decision that avoided a costly licence, followed by a budget, vendor and approvals application built in two days.

The problem
Technology spend, vendor contracts and approvals were tracked across spreadsheets and email. The obvious answer was a licensed low-code platform with a significant per-user cost.
How I approached it
- Compared the licensed platform with an in-house build on the new security framework
- Chose the build on total cost of ownership, and wrote the decision down
- Sliced the build into thin, testable increments
What was built
- Budgets, virements and forecast versions
- ERP actuals with run-rate status
- Vendors with a four-condition contract activation gate
- Approval tasks and tamper-evident ledgers
Stack
- .NET 10
- Angular
- SQL Server
- OpenTelemetry
Outcomes
- Licence cost avoided before a line of code was written
- A mobile-friendly app finance and IT both use
