// hi, I'm ksprashu

Prashanth Subrahmanyam

I build agentic AI systems that hold up in production, and help developers do the same.

Most AI work stops at the demo. I work on what comes after: agents that stay reliable with real data, at scale. Day to day that means MCP servers, multi-agent orchestration, context engineering and evals. I lead Developer Advocacy for Google Cloud across India, Southeast Asia, Japan and Greater China. Before that I spent 20 years building systems that had to work, at SAP, Apigee and Google Pay. I speak from what I've built, not what I've only read.

// nowWhat I'm working on

  • Running long, multi-agent tasks with Google Antigravity and Gemini CLI, and driving them remotely with Antigravity Remote Control.
  • Building reusable agent skills and MCP servers, collected in agent-skill-forge and gemini-cli-mcp-servers.
  • Running Builders Day, a hands-on developer format I created, in 10 APAC cities this year.
