• Experience architecting and operating event-driven systems with high availability and low latency.

• Strong background in building developer-facing APIs with a focus on usability and performance.

• Familiarity with infrastructure-as-code tools like Terraform and Helm, and GitOps/CI/CD workflows.

• Experience working in multi-cloud or hybrid environments, particularly with AWS.
