Our largest custom e-commerce engineering build. Built for PrintMont.com to handle multi-dimensional apparel customization, real-time GST tax invoicing, and automated warehouse fulfillment.
Multi-variant printing products (colors, sizes, custom print uploads, materials, corporate logo placements) created combinatorial database explosions. Standard off-the-shelf platforms suffered from 4-second load times, checkout drop-offs on mobile, and manual invoice reconciliation nightmares.
Built a custom high-performance decoupled React and PHP/MySQL commerce ecosystem with pre-calculated variation indexes. Implemented asynchronous image compression pipelines, one-step checkout with instant payment webhooks, and automated background PDF invoice generation with zero server strain.
Flattened variant lookup table eliminating 12-table SQL JOIN bottlenecks during product browsing.
Automatic server-side WebP conversion and responsive srcset generation delivered via global CDN.
Instantly generates QR-coded tax invoices, packing slips, and shipping label webhooks.
Idempotent payment webhook listeners preventing double-debits and orphan order states.
