Custom theme + Elementor
Casa Carla. Multilingual WordPress Hospitality Website
Casa Carla case study: WordPress build with Elementor, apartment content management, ACF fields and multilingual WPML IT/EN/DE setup.
Open case studyCustom development
WordPress integration and plugin development for agencies that need stable custom logic and maintainable code.
When off-the-shelf plugins are not enough, I build custom WordPress integration and plugin solutions for APIs, data synchronization and workflow automation. The technical base stays versionable and easy to support.

Outcomes
- Custom WordPress functionality built around the real project scope instead of forcing generic plugin compromises.
- Integrations with CRM, ERP, PIM, webhooks and external systems, so your WordPress site keeps talking to the tools the team already relies on.
- Code that is easier to maintain over time than fragile stacks of third-party plugin glue.
- A consistent integration pattern that scales cleanly when an agency runs the same API logic across several WordPress websites.
Plugin & Integrations
Where this service fits best
Most WordPress sites eventually hit a wall a standard plugin cannot solve on its own. It might be a CRM that needs two-way sync, a booking system with custom logic, or an internal tool that has to talk to WordPress through an API.
That is where custom WordPress integration work comes in. Instead of stacking three or four plugins that each half-solve the problem, I build one focused piece of code. It does exactly what the project needs, and nothing more.
The result is a WordPress website that stays easier to update, debug and hand off. The integration logic lives in one place, instead of being spread across mismatched settings screens.
The technical approach stays consistent across projects: a lightweight custom plugin, built on WordPress hooks and the REST API where it fits, version-controlled and documented so another developer can pick it up later. No hidden logic buried inside a page builder, and no settings scattered across five different plugin screens.

Frequently asked questions about Plugin & Integrations
What kind of plugins or integrations do you build?
I work on APIs, data sync, custom logic, forms, technical workflows and the points where a standard plugin setup no longer fits the project.
When is a custom plugin better than adding another addon?
When the project starts accumulating workarounds, unnecessary dependencies or logic that is hard to maintain. In those cases a targeted extension is usually healthier.
Can you fix integrations that are already in place?
Yes. I often step into existing integrations that need consolidation, cleanup or stronger reliability before release or further changes.
How long does a custom WordPress integration take?
It depends on the API and how much data is involved. A straightforward one-way sync can take a few days. A two-way integration with error handling and retries usually takes longer. I scope the timeline after reviewing the API documentation.
Do you work with REST APIs, webhooks and GraphQL?
Yes. Most WordPress integrations I build use the REST API or webhooks, which covers most CRM, ERP and PIM systems. GraphQL comes up less often on the WordPress side, but I can work with it when the external system requires it.
