Experience

Professional journey

  1. –present

    CI&T

    Current

    I joined CI&T working on the development and evolution of enterprise applications. During this period, I worked with APIs, microservices, and integrations using technologies such as .NET, Kotlin, Node.js, and TypeScript. I also contributed to automated testing, observability, and solutions running on AWS.

    Over time, I became more directly involved in defining and reviewing technical solutions. I currently work as a software architect on financial systems in the credit and lending domain, primarily using .NET and Google Cloud Platform. My work includes architectural decisions, integrations, technical documentation, and supporting engineering teams through implementation.

    IBM

    At IBM, I worked on the development, maintenance, and modernization of enterprise applications. I contributed to projects involving OAuth authentication and authorization, the evolution of .NET systems, and the support of applications that required close attention to security, availability, and performance.

    I also developed automation using Python, Selenium, and PowerShell, and worked on monitoring and investigating production issues. This experience broadened my understanding of operational concerns, particularly troubleshooting, maintenance, and service continuity.

    Pearson

    At Pearson, I worked on enterprise platforms related to ERP, business intelligence, franchise management, gamification, and digital content distribution. My work covered web applications, APIs, integrations, and data access components, primarily using C#, ASP.NET MVC, WCF, and SQL Server.

    I contributed to projects for email account management, secure material distribution, and integration between different systems. This period helped consolidate my experience in enterprise application development, including not only new features but also the security, maintenance, and evolution of existing systems.

    weme

    At weme, I developed portals and web applications for clients across different industries. The projects included content management systems, store locator tools, and public-facing applications built with .NET, ASP, JavaScript, and jQuery.

    I also developed data access components and integrations between applications built with different technologies. This experience deepened my work in web development and expanded my involvement in solutions that combined user interfaces, business rules, and data persistence.

    Earlier experience

    Early in my career, I worked mainly on automating administrative routines and internal processes using VBA and Visual Basic. I developed applications that supported management and operations in industrial, commercial, and pharmaceutical companies, addressing the specific needs of each environment.

    I later worked on commercial systems, electronic invoicing, web service integrations, and the migration of Visual Basic 6 applications to C#. These experiences formed the foundation of my software development career and marked the transition from automation solutions to broader applications and integrations.

Profile

About me

Portrait of Rodrigo de Oliveira

I have a degree in Systems Analysis and a teaching degree in Philosophy.

Throughout my career, I have worked both on implementing and defining technical solutions. I enjoy understanding problems, discussing alternatives, and seeing how decisions hold up during software development and operation.

Outside my professional work, I maintain open-source libraries and tools, explore new technologies, and share some of what I learn through articles and technical discussions.
