Overview
A multi-vendor e-commerce platform empowering small and medium business owners to launch and manage independent online storefronts under a unified marketplace. Each vendor manages product catalogs, orders, and financial earnings through a dedicated merchant portal, with automated revenue splitting on customer checkouts.
Problem
Local merchants struggled to establish standalone online stores due to technical complexity, prohibitive setup costs, and lack of marketing reach. Mainstream marketplace platforms charged high commission fees with rigid store customization. A localized, affordable community platform was needed to grant merchants full branding autonomy.
My Role
As the Full-Stack Developer, I architected the multi-tenant database structure, integrated the payment gateway split-payout API, and built the responsive merchant and administrative dashboards.
Technical Challenges & Solutions
Challenge: Payment Reconciliation in Split Transactions
Network interruptions during multi-party payment settlement could result in ledger inconsistencies where customer funds were deducted without corresponding vendor order dispatch.
Solusi: Implemented a robust webhook processing pipeline with idempotency keys and database transaction locks. Any transaction payload received multiple times is processed safely once, supported by automated reconciliation workers that verify settlement status every hour.
Challenge: Marketplace Query Performance
Filtering thousands of products across multiple vendors by category, price ranges, ratings, and location caused database query bottlenecks.
Solusi: Added composite database indexes, migrated from offset pagination to cursor-based pagination, and optimized Eloquent eager loading for associated relations (vendor profile, default thumbnail, aggregate reviews). Query response time dropped from 800ms to under 90ms.
Result & Impact
- 30 local merchant stores onboarded within the first 2 months of operation.
- Over 500+ successful checkout transactions completed without a single financial discrepancy.
- Participating vendors reported an average 40% increase in digital sales reach.
- Established a sustainable, recurring platform revenue model through competitive commission tiers.
