Accomplishments
- Designed and implemented a Harness log-extraction framework using PowerShell and Harness APIs to aggregate console logs across multiple pipeline stages, generating detailed execution summaries and an executive-level report with direct links to individual result sheets—improving test result visibility and traceability.
Architected a scalable parallel test-execution strategy leveraging Harness matrix pipelines with an automated rerun mechanism for failed test cases. Failed scripts were dynamically captured, stored in AWS S3, and re-executed based on user-defined retry thresholds, producing consolidated executive summaries of passed and failed tests.
Result: Reduced full regression execution time from days to hours, enabling faster release feedback cycles.
Embedded Generative AI (GitHub Copilot) into the test automation ecosystem, enabling automatic generation of test scripts directly from JIRA requirements entered as structured prompts. Enforced project-specific coding standards through a centralized Copilot instructions file.
Impact: Delivered up to 60% reduction in automation development effort compared to traditional approaches.
Built and deployed an AI-powered code review bot as a GitHub App for pull request analysis in the automation repository. The solution leveraged AWS Bedrock with Claude Sonnet 4.5, orchestrated via AWS Lambda, to perform intelligent, standards-compliant reviews.
Outcome: Significantly reduced PR review turnaround time while consistently enforcing code quality and project-specific standards in alignment with Copilot instruction rules.
Expanded GenAI-driven automation governance by introducing additional instruction artifacts, including Git commit guidelines, large-file creation strategies, mandatory review questions, and standardized prompt templates—ensuring consistency, scalability, and maintainability across the automation codebase.
Integrated JIRA Xray with the automation framework via REST APIs, enabling automatic creation and updates of Test Plans and Test Executions post-run, resulting in real-time synchronization of test results and enhanced visibility across JIRA dashboards.
