Role & Responsibilities

- Design and execute performance, load, stress, spike, soak, scalability, and failover testing for cloud-native, microservices-based healthcare applications.

- Develop realistic workload models and end-to-end user journeys based on business scenarios, SLAs, and capacity requirements.

- Create and maintain k6 performance scripts for REST, gRPC, WebSocket, and GraphQL APIs, including correlation, parameterization, checks, thresholds, and think-time modeling.

- Perform performance testing on Microsoft Azure and AKS/Kubernetes, including HPA and Cluster Autoscaler validation.

- Integrate performance tests into Azure DevOps/GitHub Actions CI/CD pipelines with automated performance thresholds and quality gates.

- Monitor and analyze application performance using Azure Application Insights, Azure Monitor, Log Analytics, KQL, Grafana, and Prometheus.

- Identify and troubleshoot performance bottlenecks across application, microservices, containers, databases, Redis cache, storage, and network layers.

- Analyze Azure SQL performance using execution plans, Query Store, DMVs, wait statistics, and indexing strategies.

- Analyze Redis cache performance, including cache hit/miss ratio, eviction behavior, latency, and connection pool utilization.

- Conduct root cause analysis for CPU, memory, GC, thread pool, database, cache, network, and infrastructure-related issues.

- Validate performance impact of HA, DR, backup/restore, TDE, replication, and autoscaling scenarios.





- Prepare clear technical and executive performance reports covering findings, risks, bottlenecks, SLA breaches, and recommendations.

- Collaborate with Development, QA, DevOps, SRE, and business teams to define performance strategies and resolve identified issues.
