TAVEN INDUSTRIES ERP
Production-Grade Manufacturing Platform
// Summary
Full-lifecycle ERP replacing spreadsheets and paper flows for a textile manufacturer in Dar es Salaam. Two live applications on a unified data model: a 12-module admin ERP spanning CRM, production, branding, inventory with FIFO batch tracking, QA, shift sessions, HR, logistics, and finance — and a customer-facing ordering portal.
// Architecture
Engineered for production reliability: HMAC-signed server actions on every mutation, role-gated access with step-up authentication for destructive operations, schema-drift guards that automatically roll back bad deploys before traffic reaches them, idempotent mutations, atomic multi-table transactions, and Decimal(12,4) precision on every currency field. Forensic audit trails on every mutation — nothing changes in the system without a record of who, what, and when.
