Portfolio
I’m the lead and architect of a mobile project for the biggest real estate of the United States. The project was built using React Native for Android and iOS. With a team size of 12 developers where I had to train some of them due to lack of knowledge on the technology. The project was done under a year of continuous work. It has deep integration with GPS and GraphQL.
I was the only front-end senior developer of a team of 2. I had the responsibility of refactoring the code to implement best practices and make the project into an MVP stage. It was built using ReactJS and MaterialUI.
I was a single developer on this project. I built a React Native APP for iOS only to handle appointments, payments, employee availability, and historical data. The main goal was to be able to reserve a service from the mobile app.
I was involved in the project since the beginning as a full stack developer. I built the backend using ExpressJS (Node) as a solo developer after I finished that I jumped into the mobile project that was being built by another developer in React Native. This project is the biggest clinical laboratory in the Dominican Republic and the main goal is to provide the user the ability to schedule appointments, ask for quotes, see their test results, etc.
I was the main technical developer of a team of 3 people. Participated in the development of a mobile app that handles loan payments using salesforce with an offline-first approach. The goal was to be able to let the loaners to digitize their data on the spot. It was built using an Ionic and salesforce SDK as their core engine. The project allowed dynamic UI and forms based on the templates created on salesforce.
