Custom development

WordPress plugin and integration development for agencies that need stable custom logic and maintainable code.

When off-the-shelf plugins are not enough, I build custom WordPress solutions for APIs, data synchronization, workflow logic and automation with a technical base that is versionable and supportable.

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 using controlled sync logic.
  • Code that is easier to maintain over time than fragile stacks of third-party plugin glue.

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.
