  • Led an Amazon Managed Grafana rollout for the DS team, moving refrigeration telemetry from a 15-minute QuickSight refresh into a near real-time, zero-staging pipeline with SAML authentication, and shipped a POC dashboard for advanced refrigeration monitoring.
  • Explored solar inverter telemetry (Active Power) using Splight and authored an anomaly-model proposal aimed at surfacing hidden cost inefficiencies across fulfillment sites, feeding the team's next-quarter modeling roadmap.
