@viniciusmaral
Junior software engineer at Telefônica Vivo automating data processing and reporting with Python and optimizing SQL queries.
BrazilWhat I'm looking for
At Telefônica Vivo, I write Python scripts to automate data processing and reporting, reducing manual effort and improving accuracy. I also build interactive Power BI dashboards and reports to support data-driven decisions.
I design and optimize SQL queries and database structures, and build backend services and APIs in C# and ASP.NET for internal applications. I deliver end-to-end features that connect backend services to data visualization and reporting.
As a Fullstack Development Intern at Telefônica Vivo, I automated router configuration and updates across Vivo’s production network using Python and Docker. I also built internal router-management tools in JavaScript and React.
My path into software began with hardware and industrial automation. At SENAI, I developed and tested embedded solutions and programmed microcontrollers; I’m studying Computer Engineering at Universidade São Judas Tadeu, with graduation expected in December 2026.
