Portrait of Anderson Costa, Software Architect and AI Engineer

01 / ABOUT

Solid engineering meets cutting-edge AI

I'm a Software Architect & AI Engineer with nearly 20 years in the .NET ecosystem, specialized in turning complex enterprise systems into scalable, secure and AI-ready platforms.

I work at the intersection of solid engineering and artificial intelligence: designing microservices architectures, integrating ERPs and legacy systems, and currently leading the AI-readiness of platforms. I expose capabilities via MCP (Model Context Protocol) to AI agents and set standards for architecture, observability and API governance. A proud self-taught engineer and technical author, driven by innovation, reliability and technical excellence.
