Working as a NodeJS back-end developer on an international and multicultural team of a north american software house company.Responsabilities:- Developing NodeJS APIs using the Express framework for a marketing campaigns application, adhering to clean code and clean architecture principles, and creating performant algorithms.- Architecting a MongoDB database for optimized storage and efficient data retrieval.- Implementing security solutions such as JWT and basic authentication, and integrating CDN components.- Working with Docker containers in a Linux environment.- Utilizing AWS S3 for cloud storage and managing version control with GIT.

Carrying out freelance web development projects of the most varied types (from payment integrations and databases to Ecommerce development).- Payment API integration using the Vindi/Yapay platform.- Authentication and authorization using OAuth 2.0 and JWT.- Development using the ERP software NetSuite (SuiteCommerce), with the SuiteScript language).Experience in projects using React, NodeJS, MongoDB and SQL database.

- Development of JavaScript/TypeScript web applications): design, develop andimplement web application features using TypeScript (with React on the front-end) that automate legal processes, manage documents and increase the efficiency of the startup's operations, creating intuitive and easy-to-use interfaces.- Server-side integration: I implement server-side integration with the React front-end application using REST API to communicate and update information that the user writes in forms.- Development and maintenance of the server in NodeJS (using the NestJS framework) to communicate with the MySQL database.- Development of unit and integration tests using the Jest framework to ensure code quality.- Docker: we dockerize both applications (front-end and back-end) to improve scalability.Maintenance and Updates: I am responsible for ensuring that all systems and applications areconsistently updated and running smoothly, minimizing downtime through the effective use of JavaScript.- Following the Agile Methodology: I follow the Agile methodology to speed up development processes,collaborating across teams and utilizing version control systems like Git for efficient code management and collaboration throughout the development lifecycle.- Git Flow: version control provided by GIT was used to ensure efficient updates and control of code updates.

RyskTech Entrepreneurial Initiation Project at UFRGS (Federal University of Rio Grande do Sul - Brazil).In this project, I used C# and Visual Studio to contribute to the creation of innovative desktop software, developed to assist in the analysis of environmental risks. The software consists of a set of forms filled in by the user whose input data is stored in a database (Microsoft SQL Server) so that a document can later be generated from them. I also used GIT and GitHub to implement version control in the project.We develop algorithms for environmental risk analysis, integrating geospatial, meteorological data sources, ecological information, chemical components and historical event data through Entity Framework and SQL Server to ensure efficient data collection and retrieval.Website development with NodeJS (JavaScript), using the Express framework and MVC architecture.We implement risk prediction models, use interactive graphs, geospatial maps and advanced data visualizations to clearly represent analysis results.We enable customization of analysis parameters, risk criteria and alerts. We implement real-time notification systems and ensure data security with robust authentication and authorization measures.We provide collaboration support, monitor application performance, and provide comprehensive user training and documentation. We conducted rigorous testing and obtained feedback from environmental risk experts to validate the tool's effectiveness.
