Over a three-month period, contributed to the OpenMeter repository by building and enhancing tax code management and billing features using Go and the ent framework. Developed a robust TaxCode data model with CRUD operations, integrated tax code handling across APIs, rate cards, and subscriptions, and implemented dual-write logic for tax codes in invoice lines to ensure data consistency. Expanded the billing domain with flexible tax configuration, metadata annotations, and improved invoice lifecycle management. Focused on database design, data modeling, and system architecture, the work emphasized data integrity, performance optimization, and maintainability, enabling scalable and compliant tax handling within billing workflows.
