• Messaging & Streaming: Apache Kafka (async messaging, event-driven architecture, latency considerations)
• Databases: SQL and NoSQL platforms (PostgreSQL, Couchbase)
• Cloud & Infrastructure: Azure (preferred, or AWS), Kubernetes (container orchestration, microservices deployment)
• Developer Productivity: Hands-on experience or adaptability with Agentic AI tooling (Tab 9, Gemini)
