# WordPress Systems

> 300+ WordPress sites across 14+ verticals, on a block theme ecosystem built for editors rather than page builders, maintained by one team.

## The Architecture

We build on our block theme architecture.

- **Core theme:** Provides the structural foundation, including layout primitives, typography system, color tokens, accessibility defaults, and responsive behavior.
- **Child themes:** Inherit this foundation and customize it for specific brands and industries.
- **Custom Gutenberg blocks:** Extend the editor with components built for each site's content.
- **Block patterns:** Pre-built page sections content editors can assemble without touching code.

One fix in the core theme reaches every site. When we improve the core system, every site on the platform benefits. When we fix an accessibility issue, it propagates. When we add a new block, it becomes available across the ecosystem. This is the difference between building websites one at a time and building a platform that produces websites.

## System-Level Tooling

- **Licensing:** Commercial and open-source licensing models for themes and plugins, with update servers and activation workflows.
- **Sandbox environments:** Isolated staging environments for client review, content migration testing, and QA. Provisioned automatically.
- **Visual regression testing:** Playwright-based screenshot comparison that runs on every deployment. If a CSS change breaks a layout on a page we did not intend to modify, we catch it before production.
- **MCP integration:** Tooling that connects our WordPress development workflow to large language models for code review, content analysis, and automated documentation.

## Custom Plugin Engineering

We build custom WordPress plugins. Our portfolio includes:

- **Payment gateway integrations:** Custom WooCommerce payment processing for regional payment providers
- **Trip filter systems:** Complex search and filter interfaces for travel booking sites with departure dates, pricing tiers, and availability
- **Departure managers:** Backend tools for managing trip departures, inventory, and booking workflows
- **SEO tooling:** Custom integrations with Rank Math and programmatic SEO pipelines
- **Multi-site management:** Centralized update management, content syndication, and reporting across site networks
