Prototyped a logic flow where incompatible blocks simply cannot connect (Error prevention by design).
Grouped variables into "Objects" and "Attributes".
Analyzed 50+ existing Groovy scripts to identify common variables
(Region, Segment, Tariff Plan).
Deconstructing the Logic
I couldn't just "draw a form."
I had to understand how the backend logic worked to translate it into a UI.
The "Groovy" Bottleneck
The billing logic relied on hard-coded Groovy scripts. To change a simple tariff commission or add a region condition, business managers had to request a developer.
Manual scripting led to critical billing mistakes.
Launching a new partner campaign took days.
Developers spent hours on routine config changes.
