Building a multi-agent AI platform for restaurant operators, deploying containerised agents to GCP Cloud Run with Google ADK as the orchestration layer. Architecting RAG pipelines over BigQuery on dbt-transformed data models that feed agent tool calls. Designed a hybrid RBAC/ACL authorization system enforced through a single Postgres auth function, scoping every agent call to the authenticated user's permissions.

We stopped treating agent latency as one number.

How we sped up Tactix Co-Pilot across the data path, tool layer, and reasoning loop — then added phase timing so we know which system owns the wait.

The agent doesn't hold the data. It decides where to go get it.

How we built a conversational analyst that fetches from gold marts over MCP — routing live across tools instead of holding the warehouse in context.
