Custom CRM & Payments Platform

Tenant-safe CRM and payment operations stack for PayU-group infrastructure — unifying wallet, merchant, and logistics channels for daily online payments across Singapore and Indonesia.

The Challenge

A PayU-group payment platform serving merchants and consumers across Singapore and Indonesia needed one tenant-safe CRM and payment operations stack. Wallet, merchant, and logistics features had grown on separate systems; high-volume daily online payment flows required predictable schema evolution without breaking live merchants or operator reconciliation workflows.

What the team delivered

The Sevendyne-engineering pod introduced tenant-scoped service boundaries: shared identity and ledger concepts, per-tenant configuration stores, and versioned REST contracts for CRM and mobile clients. Payment provider integrations were isolated behind adapter services with explicit failure domains. The back office ran on CodeIgniter/PHP with governed SQL for EMI and transaction tracking, plus companion Android and web QR payment flows used in production across APAC.
