Updates to existing WordPress themes for agencies that need layout, branding, compatibility and performance improvements without rebuilding the project.

Frequently asked questions about Existing Theme Customization

Do you also work on commercial themes or already-started themes?

Yes. I can work on child themes, overrides, templates and structural fixes across both custom themes and builds that start from an existing base.

When is customization better than rebuilding everything?

When the base is not fundamentally broken and the project mostly needs layout, brand, compatibility or quality improvements.

Can you fix layout, performance and compatibility in the same engagement?

Yes, if that is what the useful scope requires. The goal is to solve the real project problem, not split it into disconnected micro-tasks.
