Laetitia Maar

Laetitia Maar is a Cloud & AI Apps Solution Engineer at Microsoft. She takes a practical approach to modernizing legacy systems, focusing on real mainframes rather than high-level theory.

Her work bridges the gap between decades-old COBOL codebases and modern agentic AI. She builds structured prompt workflows with GitHub Copilot to reverse engineer modules, trace transaction flows, and turn tribal knowledge into something engineering teams can actually use.
