Custom themes and targeted adjustments – clean, performant, and update-safe

A well-built theme directly affects performance, usability, and conversion.
I support Shopware merchants with professional theme development, customization, and optimization – technically clean, without core hacks, and built for long-term maintainability.

Shopware 5: Theme Customization & Optimization

I do not create new themes for Shopware 5, as the system is end-of-life.
However, I continue to provide targeted adjustments to existing themes to keep shops running smoothly or to implement sensible optimizations.

Typical tasks

• Customization of existing templates and styles

• Minor design corrections

• Bug fixes and clean refactoring

• Preparation for a future migration to Shopware 6

👉 Focus: reasonable improvements without unnecessary investment

Performance Is Always a Priority

Regardless of the system, all theme work is implemented with performance in mind.

Typical measures include:

• Reducing unnecessary assets

• Clean and maintainable template structure

• Avoiding overengineering

• Strong focus on loading speed, Core Web Vitals, and maintainability

How a Theme Project Works

1. Initial review of the existing shop or design

2. Clear recommendation on what makes sense – and what doesn’t

3. Implementation in clearly defined steps

4. Review, fine-tuning, and clean handover

Transparent, structured, and without surprises.
