• Log Management: Proficiency in searching and visualizing logs via ELK Stack (Elasticsearch, Logstash, Kibana) or Splunk.

3. Systems & Infrastructure

• Architecture: Deep understanding of Microservices, Load Balancers (NGINX/F5), and Caching layers (Redis).
• Cloud & Containers: Familiarity with Docker & Kubernetes (K8s) monitoring (pod health, resource limits).
• Databases: Ability to identify slow queries and understand indexing in PostgreSQL, MySQL, or Oracle.
• Workload Modeling: Analyze production usage patterns (via Google Analytics or logs) to create realistic performance test scenarios.
• End-to-End Testing: Design and execute Load, Stress, Endurance, and Scalability tests.
