About this gig
Most developers just build standard templates. I build conversion-focused revenue engines.
If your CS-Cart store or multi-vendor marketplace is plagued by slow load times, complex checkout flows, or unstable addons, you aren't just losing visitorsyou are actively bleeding ad spend and destroying vendor trust.
As a technical CRO specialist, I don't just execute basic tasks. I architect platforms built for maximum Average Order Value (AOV) and seamless scalability. Whether you need a flawless CS Cart multi vendor store setup, complex CS Cart custom addon development, or an urgent technical intervention to fix CS Cart errors, I deliver clean, reliable, and highly optimized infrastructure.
The Grand Slam Execution (What I Deliver):
- Deep-Dive UX & Technical Diagnostics: Finding and fixing your invisible revenue leaks.
- Zero-Downtime Maintenance & Upgrades: Keeping your store secure, stable, and future-proof.
- Frictionless Cart & Custom Upsells: Maximizing AOV and customer LTV without relying on bloated, third-party apps.
- Clean, Bug-Free Code Implementation: Business-ready solutions that handle massive catalogs and high traffic seamlessly.

I am a UK based web developer who builds and fixes websites for small businesses and online stores. I work mainly with WordPress, WooCommerce, Shopify and CS Cart, and I care about pages that load fast, look clean on mobile and make it easy for customers to buy or get in touch. I communicate in writing, so every plan, update and handover is clear and saved in our Fiverr messages. Send me your link and what you want to achieve, and I will tell you honestly what I would do.

Great CS-Cart developer! He fixed my author-to-book connection, configured my addon, and got the Add to Cart button working properly. Very knowledgeable with CS-Cart multi-vendor websites and addons. Everything was tested and delivered as requested. Highly recommended!
