3. Cloud-Native Performance Engineering
- Drive performance validation on Azure cloud infrastructure with deep knowledge of Kubernetes, AKS (Azure Kubernetes Service), Docker containers.
- Optimize resource configurations (pods, autoscaling, ingress rules) to ensure resilient, high-performing clusters.
- Collaborate with DevOps to fine-tune container orchestration, networking, caching layers (Redis, CDN), and database sharding.
4. DevPerfOps and Observability
- Integrate performance validation into CI/CD pipelines using Azure DevOps.
- Leverage AppInsights, Grafana, Prometheus for live telemetry, trend analysis, and early performance risk detection.
- Establish automated alerts and feedback loops for performance degradations post-deployment.
5. Cross-Functional Collaboration
- Partner with Architects, Dev Leads, and Infra teams to triage system-level bottlenecks.
- Conduct deep-dive root cause analyses on API slowdowns, memory leaks, DB deadlocks, UI rendering lags, etc.
- Present performance findings, risk assessments, and optimization plans to leadership teams.
6. Mentorship and Scaling
- Mentor PL-based testers and interns in performance engineering techniques and tooling.
- Drive workshops and brown-bag sessions to scale performance-first culture across scrum teams.
