👋 Hi, I'm Itamar de Sá Britto Júnior

Computer Engineering | Cloud, Backend, DevOps, SRE & Observability

Building practical, portfolio-oriented projects in AWS, Linux, backend engineering, infrastructure automation, monitoring and reliability.

About Me

I am a Computer Engineering undergraduate in the final stage of graduation, currently building a practical portfolio focused on entry-level opportunities in Cloud Engineering, Backend Development, DevOps, Linux Operations and Observability.

My professional background was developed over more than 20 years in the Brazilian electric power sector, where I worked in commercial operations, administration, regional management and business process improvement.

Alongside my formal responsibilities, I designed, developed and maintained internal web applications, corporate intranets, databases and automation tools used by regional teams. This experience included requirements analysis, interface design, application development, database work, deployment, user support and production maintenance.

I am now consolidating and modernizing this experience through hands-on laboratories and portfolio projects using AWS, Linux, Terraform, Python, FastAPI, JavaScript, TypeScript, Node.js, Docker, monitoring and observability tools.

My goal is to demonstrate not only technical knowledge, but also the ability to document solutions clearly, troubleshoot problems, automate repeatable tasks and build projects that reflect real operational scenarios.


Current Stage

  • Completing my undergraduate degree in Computer Engineering;
  • Developing practical repositories for Cloud, Backend, DevOps and Observability roles;
  • Preparing for the AWS Certified Solutions Architect – Associate certification;
  • Expanding my knowledge of Terraform, Linux administration, APIs, Docker and CI/CD;
  • Developing my capstone project around an open-source observability framework;
  • Contributing to open-source projects through documentation improvements and architecture diagrams.
