Built user and driver apps with React Native, Redux, and Firebase, and developed backend functionality with Node.js and Express to deliver smooth retail logistics solutions. After the startup pivoted into Monkee, a white-label app for restaurants, I built and launched a CMS and mobile app, integrating Wompi (payment gateway) and 'Mensajeros Urbanos' for deliveries, using React Native, Firebase, and Google Maps API to improve operational efficiency.

Worked on special projects and taught web development, collaborating with 20 engineers on impactful learning projects. In my Personal Learning Environment (PLE) project, I built full-stack solutions with React.js and Golang (Gin-Gonic) and led Agile sprints with a team of 10 to ensure timely delivery.
