Middleware for financial data

sole responsible software architect and developer
|
| activities |
The goal of this project was the separation of the already developing applications
for financial data into three tiers: presentation, business logic and persistence.
This middleware delivered classes from all three tiers that could be re-used in many
projects. Just to name a few: generation of diagrams/charts (presentation),
financial calculations (business logic) and data access objects (persistence).
The project was rounded up by a clean developer documentation.
