• Build reusable test components for regression, integration, and performance testing.

AI / ML Application Validation

• Validate machine learning models by evaluating prediction accuracy against historical and real-world datasets.
• Design test strategies for forecasting, anomaly detection, and analytics pipelines used in integration platforms.

Cloud, Container & DevOps Testing

• Test applications deployed as Docker containers across multiple cloud environments.
• Contribute to Helm charts, deployment pipelines, and test environments.
• Integrate automated tests into CI/CD pipelines and DevOps workflows.

Security, Reliability & Observability

• Perform security testing using tools such as SQLMap, OWASP ZAP, and vulnerability scanners.
• Validate system reliability, fault tolerance, and recovery scenarios.
• Support observability testing using logs, metrics, and monitoring tools (e.g., Prometheus, Grafana).

Quality Leadership

• Advocate for quality-driven engineering practices and shift-left testing strategies.
• Collaborate with cross-functional teams to define test strategies aligned with product and business goals.
• Mentor junior QA engineers and contribute to continuous improvement of QA standards.
