I served as a Software Architect on a digital transformation project, building scalable and high-performance microservices in Java using Spring and Spring Boot.I heavily leveraged Azure Cloud resources, such as Key Vault for application secrets security, Application Insights for telemetry, Event Grid for event publishing and consumption, and Service Bus for pub/sub message exchange.I built Azure DevOps pipelines to implement the continuous integration and continuous deployment (CI/CD) process, streamlining the release of new versions in Kubernetes (AKS) environments and reducing downtime.I was responsible for technically leading a team of developers on the Java application project with Spring/Spring Boot, ensuring quality, efficiency, and timely delivery.I automated tests and deployments to ensure system stability and reliability across various deployment environments.I conducted code reviews, providing constructive feedback to team members to enhance code quality and foster professional growth.I actively participated in technical discussions and contributed valuable insights to address architectural challenges and make technical decisions.

Engaged in an innovative project in the construction industry, with a service architecture running on Azure Cloud and Oracle Integration Cloud. Key areas of expertise include Azure Cloud, Azure DevOps, Java, Spring Framework, Spring Boot, JHipster, Oracle Integration Cloud, Oracle VBCS, Oracle Process, and OAuth2.0.

This project presented a significant challenge due to its high complexity, involving the migration of data centers, service buses (Oracle Service Bus and Oracle SOA Suite), and the web layer (Apaches) for a major telecommunications company. My role encompassed direct involvement in the following activities:Conducting a detailed analysis of services running within each domain, including their configurations and dependencies.Tracking impacted applications and their respective network security rules.Configuring the new domain and migrating services.Orchestrating the change, which effectively marked the "switch-over" moment.Actively participating in post-migration monitoring and support, with a focus on minimizing service interruptions.This endeavor demanded a comprehensive understanding of intricate systems and meticulous planning to ensure a seamless transition while minimizing service interruptions.

I worked directly with the development and architecture of Java Web applications, SOA, and resource configuration, as well as problem resolution in Weblogic environments.I developed and designed Java Web applications, applying Java EE best practices and standards to ensure the quality and scalability of systems.I developed monitoring dashboards for integrations between various systems, using Oracle SOA Suite (BPEL, OSB, BAM) for processes. Data integration was done with Oracle Data Integrator (ODI) for large data volumes. I also configured a High Availability Weblogic environment with products like SOA Suite, OSB, BAM, and ODI.I worked on a Business Intelligence (BI) project involving the loading of large data volumes using Oracle Data Integrator.I monitored applications on the Weblogic server, including Oracle BPM, Oracle SOA Suite, Oracle Service Bus, and Oracle BAM. I also performed application deployment in production environments.I developed BPEL and ESB flows for system integration, utilizing technologies such as PL/SQL, Web Services, and Oracle Application Server. I also built applications interacting with Web Services.I developed web applications in Java using technologies like JSF, Hibernate, Spring, and AJAX4JSF, and utilized Oracle and MySQL databases.

During my time at the State Court of Auditors of Minas Gerais, I played a pivotal role in the development and enhancement of modules comprising the Electronic Certificate Issuance process. These modules were essential for the efficiency of the tribunal's operations and for serving municipalities in Minas Gerais.My primary responsibilities included:SEC (Electronic Certificate Issuance System): I led the development of this system, which enabled municipalities in Minas Gerais to efficiently and accurately issue electronic certificates. This involved creating robust features and integrating advanced technologies.SECADM (Index Update System): I was responsible for developing this system, which maintained the indices and percentages of issued certificates up to date. I ensured that the information was processed efficiently and accurately.SECVALID (Certificate Validation System): I developed this system with the aim of verifying the authenticity of issued certificates. This was crucial to ensure the integrity and reliability of the information.Technologies Used: Struts, Hibernate, Log4j, Tomcat, Oracle Database, and JDeveloper IDE.
