The Engineering Challenge

Building financial balance transactions with double-entry bookkeeping guarantees alongside complex returns management and warehouse inventory tracking.

Engineered a scalable, modern e-commerce backend utilizing a Clean Service-Oriented MVC architecture to separate heavy business logic, with Digital Wallet, Loyalty Points reward engine, RMA system, and Filament v3 administration.

  • Developed loyalty points accrual and redemption algorithms.
  • Implemented Return Merchandise Authorization (RMA) ticket workflow with automated return labels.
  • Configured interactive Filament v3 admin dashboards for inventory and store managers.

Lessons Learned & Retrospective

  • Observation #1: Financial ledgers should never perform mutable updates; only append-only debit/credit entries are allowed.
  • Observation #2: Livewire components handling bulk actions need pagination limits to prevent memory bloat.
