Profile Description
I am a Lead QA Engineer with professional experience in Software Quality Engineering across web and mobile applications. My expertise includes Manual Testing, Functional Testing, Regression Testing, Smoke Testing, End-to-End Testing, and UAT Testing within Agile Scrum environments.
I have strong experience in API Testing using Postman and backend validation through SQL database queries. I regularly perform test case design, defect management, and bug tracking using tools such as Jira and Zephyr while collaborating closely with developers, product owners, and Scrum teams to ensure high-quality releases.
In addition to manual testing, I also have foundational experience in Test Automation using TestComplete and mabl and continuously explore modern automation practices to improve testing efficiency and coverage.
I also contribute to testing modern AI-driven systems, including validating conversational AI workflows, monitoring system responses, and supporting latency and observability tracking for AI agents. This includes evaluating system responses, identifying edge cases, and ensuring reliable behavior in AI-assisted applications.
Key areas of expertise include:
• Manual Testing and Functional Testing
• Regression Testing and Smoke Testing
• API Testing (Postman)
• SQL Database Validation
• Test Automation (TestComplete / mabl)
• Test Case Design and Test Execution
• Bug Tracking and Defect Reporting
• End-to-End and UAT Testing
• Agile Scrum QA Collaboration
• Web and Mobile Application Testing
My focus is on delivering reliable, well-tested software through structured testing processes, clear documentation, and strong collaboration with development teams to ensure stable and high-quality product releases.
