Projects

Spent time debugging an issue with the Elasticsearch domain consumer in the search indexing service when the sales history consumer feature flag is enabled.

Incidents

Investigated a SEV-2 incident where sales were not appearing in Sales History for a retailer. Discovered that the Elasticsearch domain consumer was failing to process sales after enabling the sales history consumer feature flag for my demo account. The issue did not prevent sales from being created, but they were not being indexed into Sales History for retailers in the same Kafka partition. Rolled back the feature flag to restore functionality while debugging further. Created a hotfix to address the problem and plan to redeploy the feature flag once verified.

Code Reviews

Reviewed a PR to remove the customer delete icon for the delivery fulfillment type. Also reviewed the cross-team PR for rendering customization values on products in fulfillments.
