  GOVERNANÇABRASIL - GOVBR

  Jul 2020 - Jan 2021

  Senior Software Engineer

  I developed and modernized a system for issuing documents and calculating taxes, migrating from a legacy application to a robust .NET solution. I used C# and VB.NET for the backend, with Windows Forms on the frontend, integrating existing APIs to search for data and generate documents and taxes, complying with regulations such as ISS and ICMS. The data was stored in SQL Server and Oracle, hosted on AWS and managed in Azure, including CI/CD pipelines. I automated accessibility tests in Python, using frameworks such as Selenium and PyTest to ensure accuracy and reliability in the tax control of municipal governments. I implemented optimizations with data science tools such as Pandas, NumPy and Matplotlib for analysis and reporting. In addition, I integrated RabbitMQ for asynchronous processes, expanding functionalities with Angular and JavaScript, and used Git for version control. The solution was implemented on an efficient, scalable platform that is compatible with modern fiscal and technological demands. I used Ado.Net MVC, Blazor, Razor in frontend and angular.
