SaaS / AI / Shopify / GTM

App developer and vibe coder.

I am Zachary Chester, better known as BuildWithZach across social. I build revenue engines, app prototypes, Shopify tools, and product systems for SaaS and eCommerce teams. From basement exits to $3M+ generated, the through-line is turning messy ideas into real operating systems.

Operating range

From basement exits to AI products and Shopify apps.

I started by selling supplements out of a basement and bootstrapping Zero-Value to $30K MRR in 60 days. That turned into market analysis at eToro, full-cycle commerce sales at Bold, sales leadership at Avex, and founding AE work at Yofi AI.
