• Strong expertise in testing (unit, integration, etc.).
• Hands-on experience with Kubernetes, Kafka, Redis (user/admin level).
• Familiarity with AWS and/or Google Cloud for deployment and scaling.
• Experience working on the backends of large-scale B2C applications (10M+ daily active users), optimizing for high throughput and reliability.
