Worked on the openmrs/openmrs-distro-referenceapplication repository to enhance the Billing System by introducing a new ConvSet service type and overhauling the billing configuration for improved service categorization and management. Focused on configuration management, the changes replaced legacy billing setups with a modular approach, enabling more accurate billing rules and streamlined reporting. Leveraged skills in configuration management and version control to ensure the update was auditable and aligned with the product roadmap for modular billing. No bug fixes were addressed during this period, as the primary effort centered on delivering this feature and ensuring its integration into the existing system architecture.
