Need a unique feature, proprietary business logic, or a custom integration that off-the-shelf OpenCart extensions simply can't handle?

Pre-made modules often come packed with bloated code you don't need—or worse, they conflict with your custom theme and other extensions. A custom-built OpenCart extension is lightweight, secure, and tailored specifically to your exact store workflow.

With 10+ years of dedicated OpenCart backend engineering, I design and build conflict-free, upgrade-safe custom modules using native OCmod and vQmod architectures for OpenCart 2.x, 3.x, and 4.x.

What You Get:

• 100% bespoke extension development built around your exact functional requirements

• Clean, non-destructive code (OCmod / vQmod) that preserves core OpenCart files

• Intuitive Admin control panel settings (manage all configurations directly from your OpenCart dashboard)

• Full compatibility with custom themes (including Journal 3, Fastor, and custom Twig layouts)

• REST API, webhook, or external third-party service integrations

• Safe deployment and verification on your staging environment

• Clean, well-documented code with complete ownership rights

• 30-day post-delivery bug-fix warranty

Types of Custom Solutions Built:

• Custom checkout fields, conditional checkout logic, and dynamic pricing rules

• Third-party payment gateway, SMS, and logistics/shipping carrier integrations

• Custom ERP, CRM, and inventory synchronization scripts

• Customer loyalty programs, restricted wholesale/B2B portals, and tiered pricing

• Automated cron jobs, custom report generators, and admin productivity tools

Why Work With Me?
