Hi, I'm Tom. I'm a Microsoft 365 Developer & Architect. I empower developers, architects, and organizations to achive more with Microsoft 365 by creating applications and services with technologies like Microsoft Teams, Microsoft Bot Framework, Microsoft Copilot, Microsoft Graph, Adaptive Cards, and Office Add-Ins.
