- Designed the architecture of Limagrain's internal agentic platform on Google ADK / Vertex AI, supporting daily operations of the group's Data Platform (ODP): a multi-agent system (specialized agents for proposing, judging, reducing, verifying, and reporting incidents) that detects issues across 22+ monitored services (Dataform, Fivetran, Eventarc, BigQuery), classifies root causes (infra / code-bug / permission), correlates failures with recent commits, and generates actionable remediation steps, this includes Compass, an interactive ADK agent sharing the same tool surface and grounded in ODP documentation, runbooks, and naming / governance best practices (RAG), wrapped in a Next.js + CopilotKit chat UI — lets the data platform team diagnose incidents, get guidance on conventions, and unblock themselves on best practices without escalating.
- Owned the LMC Finance data product end-to-end: designed and shipped Dataform pipelines, Cloud Functions, Cloud Run jobs, and the PowerBI semantic model feeding finance reporting — full ownership from ingestion to consumption.
- Collaborated with the data platform team to roll out AI-assisted ops practices, reducing manual incident triage time.
