Hey, I'm Ganessh Kumar
Full-stack engineering, distributed systems and agentic systems.
I am a software engineer at Microsoft, working on Microsoft Fabric. I build distributed systems, agentic workflows and developer tools that make complex work easier.
Before Fabric, I worked on Microsoft Teams, including agentic workflows that reduced channel noise, notifications, lifecycle management and compliance features. Outside work, I build Obsidian plugins and run ObsidianStats.
Most of what I learn ends up here, as articles and projects. For the fuller work history, I'm on LinkedIn.
