Senior Full-Stack Engineer
About Me
I am a Senior Full-Stack Engineer with more than 20 years of experience building enterprise backend and frontend systems. My core stack includes ASP.NET Core, C#, Angular, and SQL Server, and I have spent much of my career delivering reliable, production-ready software for GovTech, HR, insurance, fintech, and other enterprise environments.
I specialize in modernizing legacy .NET MVC applications to .NET 8 while preserving business logic and minimizing regression risk. I have led incremental migration efforts, built RESTful APIs, designed scalable data layers, and worked extensively with Entity Framework Core, NHibernate, and SQL Server performance tuning.
I have also contributed strongly to frontend development, especially with Angular 8+ integrated with .NET Core backends. In addition to application development, I have implemented CI/CD pipelines using GitHub Actions and Azure DevOps, containerized services with Docker, and deployed workloads to AWS and Azure environments.
Throughout my career, I have worked in Agile/Scrum teams and collaborated closely with distributed engineering groups. I value clean architecture, code quality, unit testing, and practical delivery that supports business goals and operational stability.
My recent experience includes senior engineering roles at Vórtx, Avenue Code, Tetris Consultoria for MAG Seguros, and BASF, where I delivered modernization initiatives, API services, database logic, and enterprise portal features. I have also held technical leadership responsibilities, mentoring developers and making architectural decisions.
I am based in São Paulo, Brazil, and I am available for nearshore remote engagement aligned with U.S. business hours. I speak Portuguese natively and have professional working proficiency in English.
