Development and optimization for OpenCart 1.5–4.x and ocStore: custom modules built for your task, theme customization, integrations with payment gateways, shipping carriers, ERP/CRM systems and product feeds.
Typical work: malware cleanup with the underlying vulnerabilities closed, TTFB and Core Web Vitals improvements, cache setup (Redis, nginx), SEO fixes, safe migrations between versions and servers. Every service comes with a cost estimate before the start, a mandatory backup and verification on the live store.
