Over a two-month period, contributed to the tillhub/schemas repository by designing and implementing robust backend features focused on data integrity and export workflows. Developed a comprehensive questionnaire creation system and introduced bulk configuration batch operations, leveraging JSON Schema for precise validation and scalable configuration management. Later, built a unified data export framework supporting modular exports for payments, VAT, cashier counting, staff, customers, and goods sold, enabling standardized multi-format reporting. The work emphasized schema-driven API development, data modeling, and validation using JavaScript, resulting in improved analytics readiness and streamlined downstream integrations without introducing any bugs during the development cycle.
February 2026: Completed a unified data export framework in tillhub/schemas, introducing modular export modules and schemas for payments, VAT, cashier counting data, staff, customers, and goods sold. The work enables multi-format exports (CSV/JSON) and standardized reporting, improving data quality and analytics readiness. Seven commits corresponding to UNTIL tickets (UNTIL-18651 to UNTIL-18717) delivered module and schema definitions, paving the way for downstream integrations.
