At Target, I architected an MCP-integrated Agentic Workspace across 10 business domains and engineered an SSE token-streaming pipeline that maintained sub-100ms render responsiveness under 200K queries a day.

Previously at Tekion, I architected a collaborative digital-signing platform that replaced third-party licenses and saved $2M+ annually. At BlueStacks, I reduced time to interactive for cloud-streamed games on now.gg by 95% through Next.js hydration and browser-rendering optimizations.
