1. Complex YAML Template Structures

BNZ’s document templates involved deeply nested YAML configurations with recursive fields.
Understanding, validating, and converting these into dynamic documents required a highly flexible parsing engine.

2. Dynamic Document Generation Through Reflection

Templates needed to map directly to model fields, often nested several layers deep.
Java Reflection was used to dynamically bind values, but this introduced challenges in debugging, type handling, and predictable error tracing.

3. Testing an Entirely Dynamic System

Because templates could change anytime, defining stable unit tests was difficult.
The team engineered a testing strategy that mocked dynamic structures and validated both template parsing and data mapping.

4. Partial Legacy Architecture & Salesforce Dependency

The module had to integrate into an existing enterprise ecosystem reliant on Salesforce data models and naming conventions. Reverse-engineering existing workflows and adapting new logic without breaking dependencies required meticulous architectural planning.
