• Prepare test data by updating product attributes and adding competitors to simulate various scenarios, using 'ETL' uploads, API requests via 'Postman', or sending JSON payloads from the terminal.
• Perform manual testing of a dynamic pricing system, focusing on validating both the generation and accuracy of analytical reports.
• Verify report outputs generated via EMR jobs and stored in Amazon S3 by cross-checking them against client-provided data, using both manual review and Python (Pandas) scripts in the terminal.
• Test pricing functions and strategy logic by reviewing implementation against specifications and confirming outputs through product-level simulations.
• Query data using SQL in 'Athena' to investigate anomalies and ensure consistency across reports.
• Monitor report workflows and product runs via 'Airflow', validating execution and outcomes.
• Analyze system and job logs using 'Kibana' to identify bugs, understand failures in pricing behavior or reporting, and assist with root cause analysis.

• Developed and documented over 700 test cases for regression testing, new feature validation, and bug fixes using Xray.

• Conducted comprehensive web and client-server testing across multiple platforms, including Android, iOS, macOS, and Windows.

• Executed test cases and recorded results in Xray (via Jira), while identifying and reporting bugs using Jira's bug-tracking system.

• Analyzed internal device logs to identify root causes of errors and processed manual actions for troubleshooting.

• Participated in Agile development sprints and contributed feedback to support continuous product improvement.
