What I can do for your store
From a quick fix to a full custom build, with ongoing support after launch.
Performance is my specialty
The Core Web Vitals targets I build toward on every store.
- LCPunder 2.5 s
- INPunder 200 ms
- CLSunder 0.1
Featured Project - Fix duplicate product schema
A fixed-scope package for stores running Judge.me reviews.
Duplicate Product Schema Fix for Judge.me Stores
When your theme and Judge.me both output product structured data (JSON-LD), Google Search Console can flag duplicate or conflicting Product schema and put your rich results at risk. I find the source and clean it up.
- Schema audit of your product pages
- Duplicate markup removed at the source
- Review stars and ratings kept intact in search results
- Google Search Console errors checked and cleared
