  • At Amazon, I work on large-scale distributed systems supporting Alexa+ and global transaction platforms. I’ve owned critical backend services and infrastructure that power international launches and high-throughput financial workflows.
  • I led the international rollout of Alexa+ across multiple European regions, owning backend readiness, deployment pipelines, automated validation, and service health monitoring. These launches were executed with zero downtime while supporting millions of active users.
  • I also led a major datacenter migration from Dublin to Spain, designing fault-tolerant TypeScript-based microservices and building internal React dashboards to provide real-time migration visibility. The migration completed on schedule with no service disruption.
  • In parallel, I built a configuration-driven transaction fee platform using AWS AppConfig and microservices, enabling real-time business rule updates and supporting over $10M in daily transaction volume. I architected event-driven settlement and reconciliation pipelines processing 500K+ transactions per day using EventBridge, DynamoDB Streams, and GraphQL APIs, and modernized traffic routing by migrating legacy load balancing to AWS ALB, improving reliability and observability.
