Sioux Digital 1:1 | Hybrid
Visit company websiteResponsible for developing and maintaining modern, scalable, and high-performance web solutions, both on the frontend and backend.
On the frontend, I focus primarily on Next.js and React, with solid experience in Angular and ASP.NET Core, ensuring optimized and responsive interfaces. I use Tailwind CSS and SASS for modern and efficient styling, while also applying accessibility and performance best practices (with a focus on SEO).
On the backend, I develop applications using Node.js and ASP.NET Core Web API, integrating with REST and GraphQL APIs, and handling data in formats such as JSON and Base64. I work frequently with relational (PostgreSQL, SQL Server) and non-relational databases (MongoDB), and integrate using ORMs like Prisma and Sequelize.
I have also worked with WordPress CMS customization via PHP, created detailed technical documentation, and executed tests locally and in staging environments to ensure quality. Additionally, I contributed to version control and delivery automation using Git, and collaborated with agile teams using Scrum and Kanban, managing tasks through Jira and Trello.
About
I am a Full Stack software developer focused on Next.js, specializing in creating web and mobile experiences. I began my studies in Computer Engineering at a federal university in Rio Grande do Sul, Brazil (UNIPAMPA), with an emphasis on languages such as Java and C#, along with more technical concepts.
With the arrival of the Covid-19 pandemic and the suspension of classes, I decided to return to São Paulo and start a degree in Systems Analysis and Development at FIAP. During the course, I had the opportunity to join Sioux, where I worked as a developer for three full years in my first job in the field.
