Senior Software Engineer

I contributed to Santander's Payments Hub ecosystem, a mission-critical financial platform operating at national scale. I designed and implemented reactive Java 17 and Spring WebFlux microservices within an event-driven architecture using Kafka and AWS MSK.

I strengthened reliability through automated testing, quality gates, architectural compliance, and pre-push validation. I improved release consistency through GitHub Actions, Jenkins, and SonarQube, enhanced incident diagnosis with OpenTelemetry, Logstash, Elasticsearch, and Kibana, and mentored engineers on delivery flow and risk reduction.

I evaluated AI-generated code for correctness, maintainability, and architectural quality. I reviewed proposed solutions against engineering standards and complex software requirements.

I helped refine AI reasoning approaches and produced structured solution strategies to guide AI-assisted problem solving. My work focused on AI-assisted engineering, reasoning validation, and quality standards using Python and SQL.

I founded and led a software consultancy that delivered production systems from concept to deployment for clients across multiple domains. I delivered more than 12 production systems, including APIs, integrations, and full-stack platforms.

I led technical decisions across requirements analysis, database modeling, implementation, deployment, and CI/CD setup. I also served as a client-facing engineering advisor and introduced structured code-review and engineering standards to improve long-term maintainability.

I improved team delivery flow by reducing development waste and strengthening quality practices in legacy and evolving systems. I introduced automated testing, contributed to CI/CD adoption, and helped reduce defect rates.

I worked closely with product and business stakeholders during discovery and feedback cycles. I also facilitated internal workshops on test-driven development and DevOps practices while working with Grails, NestJS, Next.js, React Native, Angular, AWS, Azure, and relational databases.

I maintained and enhanced enterprise judicial systems used by public institutions. My work involved Java, JBoss/WildFly, TypeScript, Angular, and PostgreSQL.

I resolved complex production incidents and database inconsistencies while maintaining high code-quality standards. The team used Git, GitLab, Jira, and SonarQube for version control, delivery tracking, and quality assurance.

I developed a full-stack marketing campaign application in PHP and JavaScript, including an administrative dashboard for conversion-rate information. I also created REST and GraphQL APIs for ZIP-code lookup, Brazilian taxpayer-ID lookup, and SMS messaging.

I provided customer technical support and used client feedback to improve company websites. This role gave me end-to-end experience in requirements analysis, deployment, documentation, BPMN/Camunda, MySQL data modeling, Git/GitLab, Agile practices, SOLID, design patterns, DDD, and Onion Architecture.

I maintained client websites built with PHP, WordPress, and Joomla for organizations in multiple industries. I contributed to the maintenance and improvement of websites including educational, healthcare, condominium, and local business platforms.

I also proposed adopting task and time-management software to improve team organization and delivery coordination.

I developed and maintained Joomla-based websites and their associated databases for the Institute of Arts at the Federal University of Pará. I also supported the maintenance of computers, printers, and peripherals.

I contributed to team skill development by conducting mini-courses on HTML, CSS, and JavaScript.

I assisted the organization's clients by helping resolve technical problems during courses offered by the junior enterprise.

This internship provided hands-on experience in customer support, troubleshooting, and technical communication.
