Sharon Sobh

• Led the central performance testing function for large-scale enterprise initiatives, ensuring performance goals are aligned with business and technical stakeholders.
• Drive onboarding of new projects into the performance pipeline, assessing needs and defining test strategies.
• Partner with business, product, and technical teams to ensure performance objectives are built into delivery roadmaps.
• Conducted root cause analysis of performance bottlenecks, implemented optimization solutions, and monitored key operational metrics. Analyzed logs and system data to identify anomalies, inefficiencies, and potential issues.
• Manage and mentor an offshore performance testing team, ensuring productivity, quality, and knowledge transfer. Defined Agile/Kanban workflows, managed Jira tasks, test planning, and performed the role of Scrum Master to drive team collaboration and delivery.
• Implemented best practices in Jira and Confluence, streamlining performance testing documentation, progress tracking, and reporting.
• Delivered mentoring and knowledge-sharing sessions on performance engineering and monitoring, enabling teams to adopt best practices while influencing Product Owners to embed performance as a critical success factor in delivery.
• Implemented Grafana dashboards and alerts for KPIs, JVM, and Kafka metrics; used Dynatrace for deep-dive issue analysis.
• Performed capacity planning and scalability analysis to ensure system reliability under high load.
• Supported shift-right testing and continuous performance validation in production-like environments.
• Drove performance readiness for quarterly releases and End-of-Year peak events by executing disaster recovery and high-load testing, ensuring optimal system stability during critical business launches.

• Team Leadership & End-to-End Testing: Led a team managing performance testing from strategy to execution across web, mobile, and cloud-native platforms.
• Cloud Migration & Scalability: Optimized AWS environments (SQS, ECS, RDS, IoT Thing, Lambda) with capacity planning, load forecasting, and cost optimization for robust, scalable infrastructure.
• Collaboration & Bottleneck Resolution: Partnered with developers, architects, and DevOps to identify and resolve performance bottlenecks, ensuring high availability and low latency.
• CI/CD Integration & Shift-Left/Right Testing: Integrated performance tests into Jenkins pipelines using Taurus and BlazeMeter; implemented shift-left/right testing for continuous performance validation.
• Application Coverage: Conducted end-to-end performance testing of mobile apps, APIs, message queues (ActiveMQ, IBM MQ), and UI applications (B2B, B2C, portals).
• Mobile App Performance: Performed automated performance testing using NeoLoad and JMeter, simulating real-world load to improve responsiveness and stability.

• Defined performance objectives with stakeholders and ensured alignment with business requirements.
• Designed and executed web and mobile tests (Perfecto), simulating realistic user load and interactions.
• Analyzed results, identified bottlenecks, and recommended optimizations for stability, scalability, and responsiveness.
• Validated overall application reliability under varying load conditions.

• Created and enhanced LoadRunner scripts (VuGen) with parameterization, correlation, and real-world scenario simulation.
• Executed performance tests using HP Performance Centre, defining ramp-up/ramp-down of virtual users and preparing test suites.
• Analysed results using metrics like CPU, memory, disk, throughput, response times, web/database monitors, and heap/Garbage Collection behaviour.
• Identified performance bottlenecks, memory leaks, and coordinated with development teams for issue resolution.
• Conducted various tests: load, stress, spike, endurance, regression, mobile, batch, and resilience/recoverability testing.
• Generated performance reports and graphs to provide actionable insights and recommendations.
• Experienced in performance testing of PEGA and cloud-based applications.
