This software is a 15+ year-old system that required advanced programming skills and a deep understanding of deployment and infrastructure management. I spearheaded a comprehensive refactoring initiative aimed at enhancing software maintainability and reducing bug incidence.The refactoring process involved implementing rigorous testing strategies, including unit tests, integration tests, and performance tests, to ensure the software’s reliability and quality. Additionally, I optimized data ingestion and processing to improve performance and began adapting the solution for Linux environments while integrating advanced features like Artificial Intelligence.The challenge is ongoing, as I have not yet completed all the refactoring or made the solution fully operational on Linux. To date, I have successfully finished refactoring a core module of the solution. Leading this project required strong leadership and initiative. I effectively managed a global, remote team, demonstrating excellent communication skills to bridge time zone differences and align diverse stakeholders. My problem-solving approach was pragmatic, addressing issues proactively and balancing technical excellence with real-world constraints. Throughout the project, I maintained a customer-centric focus, ensuring that enhancements and bug fixes were handled efficiently without disrupting ongoing operations. This ongoing work underscores my commitment to driving complex projects to successful completion while fostering a collaborative and productive team environment. Show less

I worked on a project for a major Brazilian company that manufactures cardboard boxes. Despite my strong programming skills, I needed to deepen my understanding of development solutions and architecture to think like a senior developer.The project faced significant issues: the software was poorly designed, lacked proper unit and integration testing, and had high coupling with no clear separation of concerns or layers. The focus was primarily on bug fixes rather than new features, and the project was not even in production yet. I joined the team 1.5 years after development had begun and spent 6 months working on a project that seemed destined to fail.This experience highlighted the importance of good architectural practices and motivated me to enhance my skills in this area. I committed to improving my architectural knowledge to ensure that I would never be involved in a project with such fundamental design flaws again. Show less
