Shopify — Custom apps
Custom apps when the platform lacks the feature: own logic wired into the admin and the storefront.
eCommerce Implementer · Córdoba, AR
I ship eCommerce. And I code what the platform can’t do.
I’m Gabriel «Gabo» Pérez — senior Shopify & PrestaShop implementer at Wualá. I own the project end to end: planning, custom development, client training and go-live.

01 — About
From a design eye to technical execution
Implementer + developer + trainer
I didn’t start in code: I began in design and communication, moved into content and brand management, and ended up implementing eCommerce end to end. That mix is why I understand the client’s business before I touch a single line.
I don’t just configure platforms. I build custom Shopify apps, themes from scratch on the Horizon architecture, PrestaShop modules and automations when the platform falls short. When there’s no ready-made solution, I build it.
And I train. I coach SMB owners and their teams to run their store autonomously, without depending on external support for every change.
