What I'm looking for

I'm open to Principal, Staff, and Tech Lead roles.

At Four Seasons Hotels & Resorts, I lead AI engineering and platform architecture for Golden Eagle, an AI-powered concierge and hotel discovery platform. I designed its five-layer multi-agent pipeline and built hotel discovery around multi-vector semantic search fused with Reciprocal Rank Fusion.

I also designed and delivered a production MCP server in C# on Azure, connecting the platform to ChatGPT and Claude with interactive search, room-rate, add-on, and map widgets. I established engineering standards and architecture governance for the AI platform team, alongside its observability and CI/CD stack.

Before Four Seasons, I architected AI agent and analytics platforms at MayAI and Valco AI, and a multi-agent code review platform at DevGuardian AI. Earlier, I designed enterprise systems across banking, travel, lending, CMS, and IoT, including a telemetry platform for the Department of National Defence Canada and banking platforms through Tajan, which was acquired by Mellat Bank.
