High-Traffic E-Commerce Platform
Developed and supported an e-commerce platform handling roughly 25,000 SKUs and 3,000+ daily orders, plus a live-bidding auction platform, covering checkout, inventory, payments, and a dozen external integrations.
High-volume e-commerce leaves nowhere to hide: every slow query and every integration hiccup shows up in revenue.
The work
I developed and supported a platform with a catalog of roughly 25,000 SKUs processing 3,000+ orders a day, covering customer accounts, checkout, order processing, and inventory operations. I also built a live-bidding auction platform handling about 300 concurrent active listings, and integrated payment gateways, shipping providers, and inventory sync APIs across more than 12 external services.
The outcome
Faster pages through PHP refactoring, query optimization, and caching, and an order pipeline that stayed dependable at thousands of orders per day.
