Hevert Gelis · React Native developer · iOS and Android

I ship mobile apps to the App Store and Google Play, and keep them running.

I migrated Aludra Ventas Asistidas from native Java to React Native, feature by feature, and shipped it to both stores. Before that I built the login and home of the Chedraui app, integrated Pepe Ganga's payments and contributed to Framework II, a framework for building apps from declarative JSON.

    Aludra Ventas Asistidas

    Cochez y Cía · Panama · iOS & Android

    Ventas Asistidas (assisted sales) is the platform Cochez sales associates use to guide each customer through an in-store purchase: they check stock at every branch, build quotes, manage customers, estimate the materials a project needs and share current promotions. My part was the mobile app the associate carries on the store floor: I migrated it entirely from native Java to React Native, feature by feature, with voice and camera search, quotes and price-tag printing, and shipped it to the App Store and Google Play.
