I am a backend software engineer with over 5 years of experience building scalable enterprise systems, primarily using Java and the Spring ecosystem. Currently based in Brazil with full professional proficiency in English, I am seeking international opportunities where I can contribute my expertise in microservices architecture and distributed systems. My technical foundation includes deep experience with Java, Spring Boot, Spring Batch, and microservices architecture. I specialize in designing RESTful APIs, implementing asynchronous processing systems, and working with relational databases (PostgreSQL, SQL Server, Oracle) and cloud platforms (AWS, Azure). I adapt quickly to new technologies and thrive in complex technical environments, having successfully worked across telecommunications, insurance, and retail domains. As senior software engineer for the Insurance Hub at Compass.uol, I designed and implemented a product projected to generate R$ 35 million in revenue per product over five years. I've also led successful migrations from monolithic to microservices architectures and consistently improved system performance and reliability in production environments handling critical operations. I value clear communication and collaboration, which has enabled me to work effectively with both technical teams and business stakeholders. I'm a fast learner who stays open and flexible to new technologies and approaches, always looking to expand my skill set and adapt to different technical contexts. I'm excited about the opportunity to contribute to your team and grow alongside talented professionals.

Employment History

Senior Software Engineer at Compass.uol Current 2024 - Now
• Tech Lead for the Insurance Hub squad, responsible for guiding an inexperienced team through complex architectural decisions. Led the evolution to a hexagonal architecture with partner-specific middleware layers for scalable integrations, while actively mentoring team members and helping them grow professionally alongside the project. • Designed and implemented a policy issuance API combining synchronous and asynchronous processing to deliver fast customer responses while handling enrollment in the background. The product is expected to generate approximately R$ 35 million in revenue per insurance product over the next five years. • Built a partner payment notification API to ingest encrypted fixed-length files, persist payment data, and process notifications via scheduled batch jobs, ensuring reliability, traceability, and operational control over payment flows.
Software Engineer at CISS S.A 2022 - 2024
• Worked on the evolution of the core retail management system, enhancing a microservices-based architecture that supports highly critical financial and accounting processes for retail operations, using Java and Spring Boot. • Collaborated closely with financial and maintenance teams to develop and maintain backend services responsible for business rules, system integrations, and financial data processing, leveraging Spring Data, JPA/Hibernate, and SQL Server. • Implemented improvements focused on performance, resilience, and reliability, including code optimizations, failure handling, and production support, contributing to increased system stability and reduced incidents in production environments.
Software Engineer at Objective 2020 - 2022
• Contributed to the modernization of CRM and Billing systems for the telecommunications domain, actively supporting the transition from a legacy monolithic architecture to a microservices-based architecture. • Designed and implemented key backend features and system integrations, enabling decoupled services, improved scalability, and smoother interoperability between legacy and modern components. • Improved overall scalability, maintainability, and long-term sustainability of the platform by applying best practices in service design, code organization, and architectural evolution during the migration process.
