Carlos Machel

Microsoft MVP (.NET) · AI Engineer

I build AI agents in C# with the Microsoft Agent Framework and Microsoft Foundry, and I teach how to do it: tools, memory, RAG, workflows, evaluation and observability, on real business scenarios.

Website · LinkedIn · AzureBrasil.Cloud

▶️ YouTube playlists: Microsoft Agent Framework · Microsoft Foundry · Series hub (code for every episode)

In numbers

  • 30+ episodes of the Microsoft Agent Framework series on AzureBrasil.Cloud, each with runnable .NET code
  • 5 talks and lives in 2025–2026 about agents in .NET
  • Recent samples run on .NET 10 with Entra ID auth (DefaultAzureCredential), no API keys

Featured work

Project What it shows
MAF video series hub Every episode of the series, with code and video, from basic agents to hosted agents
Permission-aware RAG RAG where each user only gets answers from documents they can access, enforced in SQL Server 2025 VECTOR queries
Multi-agent credit assessment Parallel agents (credit, KYC, fraud, income) orchestrated in a workflow
Evaluating AI agents Evaluating agent quality and tool calling with Microsoft Foundry
Code review agent via MCP Agent that reviews C# using a Foundry Toolbox backed by Roslyn Analyzers over MCP
