I’m a senior front-end developer building scalable, accessible web and mobile UIs.
ColombiaWhat I'm looking for
I’m a front-end developer focused on building reliable user experiences across complex platforms—web, e-commerce, and mobile. I’ve worked on intelligent contact solutions with chatbot systems across major chat channels, connecting modern UIs to back-end services developed in C#.
At Take/Blip, I helped deliver front-end experiences for mobile apps and interactive chat journeys, using VueJS, React-Native, and later Flutter. I care about creating interfaces that feel consistent and dependable even when integrations and channels vary.
At RD RaiaDrogasil, I built the front-end for Magenta 2 e-commerce across multiple pharmacies using a common UI and theme-based layout changes. I used React JS with Styled-components, GraphQL for data querying, and a BFF approach for front/back interaction, organized as a single repository divided into packages with Lerna.
Earlier, I delivered React-based web apps for Latoex platforms and supported customizations for WordPress websites, including creating Vanilla Javascript scripts for a ContaZap WhatsApp Chatbot. I’ve also created and maintained websites and web apps using a broad toolkit (from HTML5/CSS/SCSS to Node.js, Bootstrap, jQuery, and WordPress theme development), including freelance work involving Joomla!, WordPress, Magento, and Symfony.
