🏆 In May 2025, I received the Microsoft MVP award in the "Developer Technologies" category. In Brazil, only 22 people have been awarded in this category through "Web Development" Technology Area until May 2025. It means 0.000407% of brazilian developers.
The Microsoft MVP program globally recognizes exceptional technical leaders for their deep knowledge, expertise, and influence. Through voluntary and high-impact contributions, MVPs transform communities and solve real-world problems, especially within the Microsoft technologies ecosystem.
