I made the app with an app engine, sand it was supported in the Apple Store and Play Store. My learning curve was steep, because I needed to learn many new variables about a startup; starting from an idea, and then speaking with the possible final users to further understand their needs, and finally transforming those requirements into features on the app. ## Education ### desarrollador fullstack in Informatics Coderhouse Jan 2015 – Jan 2015 ### MOOC in Marketing edX Jan 2013 – Jan 2016 ## Contact & Social - LinkedIn: https://linkedin.com/in/charlbarrera --- Source: https://flows.cv/carloscharlbarrera JSON Resume: https://flows.cv/carloscharlbarrera/resume.json Last updated: 2026-04-01
