Performance Engineer

• Executed performance measurements, collected all necessary performance data, conducted performance analysis, and shared results with the team.
• Managed workload script generation, script review, performance analysis, defect logging, tracking, and regression scheduling.
• Analyzed various performance issues such as Out of Memory (OOM), high CPU usage, thread deadlocks, database problems, and memory issues.
• Profiled slow-performing transactions, identified root causes, and recommended fixes.
• Oversaw environment data population to align with production growth.
• Coordinated and communicated with other test environments/teams and the development team regarding performance capacity, findings, issues, fixes, and recommendations.
• Administered and managed a medium-scale distributed performance environment with over 40 servers, addressing patching issues, debugging functional and performance problems, and scheduling and coordinating with the team to optimize environment usage.
• Developed automation tools and processes to streamline performance measurements and analysis.
• Collaborated with DevOps to communicate performance recommendations for application tuning and scaling, and opened subsequent tasks and defects to incorporate them into the automated deployment framework.
• Mentored team members and provided guidance to other teams for addressing performance, functional, design, and code issues.

Senior Performance Engineer

• Led sprint planning sessions, sprint reviews, and retrospectives, collaborating with product owners for story reviews and acceptance.
• Created dashboards in Jira to monitor the team's velocity, burndown charts, project progress, and bug tracking.
• Designed and implemented interactive Splunk dashboards to collect relevant production metrics, enabling the team to quickly identify testing gaps and conduct capacity analysis.
• Increased team productivity by automating time-consuming tasks such as test data creation (using shell scripts) and test report generation (utilizing templates).
• Developed testing methodologies for the entire team to comprehensively stress the application at every interface and identify potential breaking points.
• Enhanced the application's scalability by fine-tuning JVM memory settings (Java J2EE on Linux VMs) and ActiveMQ thread pool settings.
• Detected critical errors and memory leaks within the application by monitoring application server logs, analyzing garbage collection data (using dynaTrace memory dumps and thread dumps).

Performance Engineer

• Responsible for gathering requirements, developing test plans, and planning, conducting, and executing performance tests. Assisted technical leads in resolving performance-related issues.
• Enhanced Vuser scripts in LoadRunner by implementing Parameterization, Correlation, Transaction points, check points, and rendezvous points, among others.
• Conducted performance testing on a web-based application for bank loan information, which was used for requesting and approving mortgage loan requests.
• Executed the application with different protocols, including AJAX, Web(HTTP/HTML), Citrix, and Java over HTTP.
• Actively participated in Scrum meetings and reviews, and developed test scenarios.
• Modified Truclient scripts with Java code snippets for page verification and object identification.
• Assisted developers with test files and test data, and executed SQL queries to ensure data integrity.
• Created and updated the workload model for load testing after analyzing production data.
• Uploaded scripts, created timeslots, scenarios, and ran load tests in Performance Center (ALM).
• Utilized Dynatrace to monitor backend application servers and database servers to identify potential performance bottlenecks during test execution.
• Prepared a final executive summary report at the end of the engagement.

Senior Systems Performance Engineer

• Designed and implemented a comprehensive automation framework using Python for performance testing of the AppResponse Xpert product. This initiative involved transitioning from manual to automated testing of the product.
• Conceptualized and introduced a robust performance monitoring tool that operates on the appliance, effectively collecting and managing statistics.
• Created and managed an internal website accessible to support and other internal teams. This platform allowed them to view monitored statistics and customer data, aiding in issue troubleshooting and serving as a primary information source for understanding customer workloads.

Drilling Performance Engineer

• Pioneered the implementation of Drilling KPIs, aligning them with international standards to measure dry hole performance effectively. Established the methodology required for constructing a comprehensive dry hole performance database, encompassing over 4000 wells.
• Generated the initial dry-hole performance reports, incorporating performance metrics and rankings.
• Developed the first interactive performance dashboards using Power BI, granting direct access to performance insights for the Exploration and Drilling directorate. These dashboards covered various analyses, including Dry Hole Performance, NPT Analysis, Rig Move Analysis, Workover Performance Analysis, Contractor Performance Ranking, Bit Performance Analysis, Well Planning, Duration Estimation, and Cost per Foot Analysis.
• Collaborated on the inaugural Artificial Intelligence and Machine Learning project introduced at KOC. This initiative, conducted in partnership with the Information Technology Services Team and Microsoft, focused on low-frequency operational classification and analysis.
