CV
I'm not just a developer — I'm an entrepreneur who spent 28 years running my own e-commerce business (30,000+ SKU store on OpenCart) and built a complete ERP system from scratch (PHP/MySQL/Redis) that processed 100,000+ orders. That means I understand your business, not just your code. When you say "we're losing orders" or "the site slows down during sales," I know exactly what that costs you — because I've been there. What I do: • OpenCart: custom modules, bug fixing, version migration (3.x to 4.x), performance optimization • API integrations: marketplaces, shipping carriers, payment gateways, accounting systems • Catalog parsing & automation (products, prices, stock sync from suppliers) • Custom ERP/CRM development or improving existing systems • Server administration (Linux, scaling under load) I work step-by-step with verification at each stage. I don't disappear. And I'm honest: if your task takes an hour, I'll tell you — I won't stretch it out.
