May 2026 was focused on reducing technical debt and improving data access safety and PostgreSQL compatibility through ORM-based refactors and a broader database modernization effort. Key work spanned two ERP repos (frappe/erpnext and aerele/erpnext), emphasizing maintainability, readability, and safer data access patterns across critical procurement and supplier workflows. Highlights include: ORM-based data access improvements across supplier scorecard standings, reserved quantity calculations, and minimum order quantity retrieval in frappe/erpnext; replacement of raw SQL and IF logic with frappe.get_all and PostgreSQL-friendly constructs; a major shift to an ORM/query-builder approach across multiple supplier/material-request modules in aerele/erpnext; and targeted fixes to ensure PostgreSQL compatibility. Business value realized: reduced SQL customization, safer and more auditable data access, easier future refactoring, and stronger cross-module consistency for procurement analytics and supplier interactions. Technologies demonstrated include Frappé ORM, frappe.get_all, Frappé Query Builder, PostgreSQL-aware refactoring, and Python code quality improvements.
