ShopWave (E-Commerce)
Multi-vendor marketplace scaled from 6s page loads to sub-second, lifting checkout conversions by 68%.
THE CHALLENGE
The client ran a slow, monolithic marketplace on shared hosting — 6-second page loads, frequent crashes under 200 concurrent users, no payment integration and a checkout flow customers abandoned.
HOW WE SOLVED IT
We re-architected on a modular PHP + PDO codebase with an MVC-style structure, cached queries and lazy-loaded product images. Built a secure multi-vendor flow with Bkash/Nagad gateway abstraction, JWT-style auth, role-based dashboards and a PWA service worker for offline-first mobile access.
