About

Professional summary

I am a Senior Software Engineer with more than 20 years of experience modernizing complex enterprise systems, designing maintainable architectures, and delivering reliable software for regulated and high-volume environments.

I currently build enterprise solutions for European Commission projects at NTT DATA. My work includes EU-wide regulatory systems, legacy modernization, REST API architecture, cloud integrations, and full-stack delivery for services used by all EU member states and global suppliers.

My core technical background is in Java, Spring Boot, JEE, microservices, AWS, Angular, REST APIs, and Docker. I apply Domain-Driven Design, Test-Driven Development, Spec-Driven Development, and agile practices to build software that teams can support over the long term.

I have delivered systems for major financial institutions in Brazil, including credit-risk platforms, document-management solutions, workflow systems, and high-volume transactional applications. I have also led developers, mentored junior engineers, and helped teams improve quality, delivery speed, testing, and deployment practices.

I use AI-assisted development to accelerate code reviews, refactoring, test coverage, and feature delivery while maintaining engineering standards. I am seeking a Senior Software Engineer role focused on enterprise modernization, backend architecture, cloud solutions, and high-impact projects.

Career history

Senior Software Engineer | Fullstack NTT DATA

I deliver enterprise solutions for European Commission projects, specializing in legacy modernization, API architecture, and cloud solutions for EU-wide regulatory systems. My work supports regulatory processes used by all EU member states and global suppliers.

For EUDR, I introduced AI-assisted development with Kiro IDE, reduced software defects by 9%, delivered six critical compliance features, and architected REST APIs integrating external environmental-monitoring systems. I also designed SOAP/REST integration layers and an AWS S3 storage architecture.

Across Ecolabel, Sygma, and Decide Replies projects, I delivered business features, built AWS-based Spring Boot microservices, migrated 19 JSP screens to Angular, designed 23 REST APIs, and established engineering practices for distributed teams.

Senior Software Engineer CTS – Centro de Tecnologia de Software

I built enterprise document-management and workflow solutions for Sicoob, Brazil's largest cooperative credit network. The platform processed more than two million documents daily across a large nationwide banking network.

I developed features and scheduled jobs, designed real-time enterprise integrations with Apache Camel and Kafka, and refactored core modules. I expanded unit-test coverage to 72% and implemented proactive monitoring and performance optimization, reducing production incidents by 6%.

Senior Software Engineer | Fullstack BB Tecnologia e Serviços

I combined hands-on software development with technical leadership for Brazil's largest financial institution. I contributed to architecture, requirements analysis, implementation, testing, and delivery for high-volume transactional systems.

I led a team of four developers during the team leader's absence and mentored two junior developers who progressed to mid-level roles. I architected the QGD system for maintenance scheduling across 3,900+ branches and implemented CI/CD pipelines that reduced build times by 12% and increased releases from biweekly to twice weekly.

Senior Software Engineer | Tech Lead Ci&T

I served as a Tech Lead, providing hands-on development, architectural support, and team leadership for financial-services clients. I led a five-developer team delivering a client-scoring system for Votorantim Bank covering 4.2 million customers and a R$97 billion portfolio.

I improved credit-scoring algorithms, contributing to a 2.1% reduction in loan defaults. I mentored developers on coding and testing practices, helped achieve 63% test coverage, and introduced Kanban to reduce delivery cycles from 14 days to 5 days.

Senior Software Engineer BS Services

I developed an enterprise credit-risk platform for Banco da Amazônia, deployed across 124 branches and used by more than 2,000 users. The platform processed R$488.4 million in rural credit operations during 2010.

I built guarantees and collateral maintenance, disbursement processing, and rural-credit project intake functionality. I also applied performance optimization that improved rural-credit acquisition project processing time by 8%.
