• I work in backend development with Java and Spring for an internal platform that reduces operating costs and accelerates high-quality deliveries for all of the bank’s engineering teams, effectively minimizing critical production incidents. • I worked on the development of a Lambda Authorizer to handle authentication and authorization in conjunction with the API Gateway, using Python with FastAPI. • I evolved the integration with the automated testing service, allowing the upload of multiple scripts with different extensions in S3 buckets, increasing test coverage and delivery quality, resulting in a 38% increase in the integrated test quality indicator. • Automated the linking of multiple test scenarios to Experience Management Task IDs, reducing manual effort and improving traceability. • Responsible for provisioning infrastructure on AWS via Terraform (Infrastructure as Code), integrating application deployment with CI/CD pipelines, and ensuring scalable, versioned, and auditable environments.

Business Domain: Cards My work is based on Fullstack development, with a focus on creating and evolving solutions for the Card domain in service channels (Agency and Call Centers). Backend: - Development of applications with Java and Spring Boot, from middleware that simplifies communication between services and abstracts information for the frontend, to more robust systems structured with a clean, hexagonal architecture, striving for scalability and easy maintenance. - Docker container orchestration with Kubernetes, automating deployment and management processes in cloud environments such as AWS, OpenShift, and Azure. - Application logs monitoring with Kibana. Frontend: - Evolution of legacy applications to the Micro-Frontends architecture in Angular, in order to bring more modularity to applications in the channels. For both stacks, we use CI/CD practices on a daily basis with GitHub Actions and Jenkins to ensure continuous deliveries with quality and security. Technologies: Java, Spring Boot, Angular, TypeScript, Micro-Frontends, Hexagonal Architecture, Clean Architecture, Docker, Kubernetes, AWS, OpenShift, Azure, GitHub Actions, Jenkins, CI/CD, Agile Methodologies.

I worked as a Software Engineer on a global Mastercard project, contributing to the construction and evolution of systems responsible for communication between the card processor and customers consuming the services, with a focus on performance, scalability, and security. Main responsibilities: - Microservices development with Java and Spring Boot, following distributed architecture best practices. - Systems integration via messaging with Apache Kafka and Amazon SQS, ensuring asynchronous, scalable, and resilient communication. - Deployment and management of applications in an AWS environment. - Participation in code reviews, technical refinement of requirements, and architectural definitions, working with international teams. - Active collaboration with teams from different countries (Ireland, India, the USA, and Brazil), with communication entirely in English, both written and spoken. Results and Impacts: - Contributed to the development of a reliable and scalable infrastructure between Mastercard's global systems and partners. - Gained experience in large-scale, high-volume transaction projects, meeting the quality standards required by a regulated environment. - Strengthened skills in international communication, multicultural collaboration, and technical performance under global requirements.

As a software development intern, I work on full-stack tasks within the Cards team, ranging from developing automated Web, Mobile, and API tests using the BDD (Gherkin) methodology, back-end development focused on Middleware development with Java and Spring Boot, to front-end development with bug fixes in the channels used by agencies and call centers in Angular.
