My work involves specializing in big data processing with Node.js and Ruby on Rails, designing and optimizing data pipelines to handle large-scale data, integrating advanced analytics, and ensuring seamless performance in scalable web applications. I leverage both frameworks to deliver efficient and reliable data solutions.

I designed and developed innovative features for a Learning Management System (LMS) using TypeScript, Angular, GraphQL, and Ruby on Rails, which helped boost user engagement and improve learning experiences. I also optimized a custom reporting system with scheduling and recurring reports using SQL, Ruby on Rails, and Treetop, enhancing reporting accuracy and performance. Along the way, I mentored junior developers and conducted code reviews, promoting best practices and continuous improvement within the team. I'm passionate about building impactful software and helping teams grow.

I worked on building and launching new features for a property management web system used by over 2,200 clients, using TypeScript, React.js, and Ruby on Rails to boost client satisfaction and engagement. I also led bug fixes and performance improvements, cutting down system downtime and making the user experience smoother with efficient debugging and testing using JavaScript and Git. On the infrastructure side, I handled server maintenance and database optimization with Docker, AWS, and PostgreSQL, keeping the system robust and scalable. I teamed up with the business side to turn their requirements into technical solutions, making sure our work was always aligned with the company's goals. For the last two years, I managed a team of developers, overseeing project delivery, mentoring team members, and keeping everyone on track with best practices and quality standards.

In my role within a software house model, I took on diverse projects where my primary focus was on constructing and rigorously testing APIs and web applications. Notably, I played a crucial role in two major projects: Pfizer PROConnect and Loghub. My responsibilities included the end-to-end development process, ensuring the robustness and efficiency of the APIs, as well as the seamless functionality of the web applications. Through these experiences, I honed my skills in delivering high-quality software solutions in line with industry best practices.

During my tenure at a financial services firm, I played a pivotal role in managing a receivables system that interfaced with major financial institutions, including JP Morgan, Tokyo Bank, Citibank, and various prominent Brazilian banks. In this capacity, my responsibilities revolved around the implementation of new functionalities and the continuous enhancement of the system's architecture.Working primarily with a technology stack centered on .NET, I contributed to the development of versatile applications tailored to the intricate needs of the financial sector. The database management aspect involved utilizing Microsoft database technologies, specifically SQL Server, to ensure the security and efficiency of data handling.My proactive engagement in refining the system's capabilities and architecture was integral to its success in meeting the stringent standards of the financial industry. This experience not only showcased my technical proficiency but also highlighted my ability to navigate and contribute effectively to the complexities inherent in financial technology solutions.
