EXPERIENCE
September 2023 - Present
Web App Developer - Remote
Development of an innovative platform using React JS and Node JS technologies,
together with the Next and Express frameworks. This project aims to create a robust
process management and equipment repair platform, offering a comprehensive solution
for company daily operational needs. Additionally, it has features that allow users
to access other relevant platforms and obtain crucial information about essential
procedures to optimize business operations.
To ensure the reliability of APIs, I am employing Postman for testing. Postman provides
a user-friendly interface for creating, testing, and documenting APIs, streamlining the
validation and debugging of requests and responses.
Database management is handled through PostgreSQL, an open-source relational
database management system, with pgAdmin serving as the graphical administration
tool, simplifying configuration and maintenance tasks.
These technological choices and security measures align with the goal of developing a
robust, efficient, and secure project, providing a positive user experience.
