Experience
Calendar Event System for Adobe
Created a calendar event system using JavaScript and jQuery for handling live events and timezones from more than 50 countries. It was created as a system for IXDD (World Interaction Design Day) for Adobe.
FOREX Signal App Platform
A React platform for understanding and using FOREX Signals created by the trendy trade team. I was part of the front-end and back-end development team. For the front-end app, my responsibilities were to implement the Illustrator designs created by the design team and make sure the implementation of the design was pixel perfect. I also implemented detailed CSS3 animations with the look and feel of the company to provide the user with a pro experience. As part of the project, I implemented the functionalities of allowing a user to log in, fetch all of the information of the signals, and store and save as favorites. In addition, I implemented a notification service that allowed users to buy and sell FOREX currencies based on live data.
Web Application for Biggest LATAM Lawyer Association
A React app for showing events and information for an important association of LATAM lawyers. It implemented an Express.js/Node.js back end for storing user information and creating and storing events. I was responsible for leading a small team in creating the front-end web app and coding requirements of the back end and front end. I coded the functionalities for storing and creating events, fetching user information, and an informative map for showing all locations of associated lawyer brands in LATAM.

A React web app was created for the landing site of a FOREX signal website. I implemented tracking events, the design elements from Illustrator, and information elements from the site. It allows for the registration of potential new customers.
Website with Shopping Cart for a Jewelry Brand

A React Native app in the App Store called HeartPoo was created for rating consumer experiences. It ultimately processed 1,000 new posts daily and achieved more than 10,000 downloads in the first month.
