Summary
👤
Senior🎓
Top SchoolLeniel Maccaferri is a versatile software engineer with 14 years of hands-on experience building end-to-end web systems, primarily on the Microsoft stack (.NET Core, C#) and modern front-end frameworks like React and Angular. A dual Brazilian-Italian citizen based in Rio de Janeiro, he blends deep technical architecture skills with practical delivery as an independent consultant and remote full‑stack contributor to global teams. His background spans data integration, ETL, cloud identity (Azure AD B2C/IEF), SQL Server automation, and Power BI reporting, showing strength in both backend systems and analytics. Leniel is pragmatic and code-first—comfortable defining architectures and implementing them himself—and maintains an active StackOverflow presence that reflects his problem-solving focus. Less obvious: his early work in HPC and parallel C++ systems gives him a strong foundation for performance-sensitive and distributed applications.
