Built an internal QA assistant for Cisco\'s ISE product using OpenAI GPT-4, LangChain, and FastAPI to allow QA engineers to query product documentation, test case histories, and troubleshooting guides. Integrated vector search using FAISS for context retrieval, improving accuracy in responses. Reduced manual document searches from 10+ minutes to under 30 seconds during test case analysis, significantly reducing manual bug verification efforts and enhancing ease of delivery of hot fixes.Built an AI log analyzer to identify product failures from the mainline automation console logs. Leveraged SBERT embeddings, scikit-learn, Python, and Pytorch for this analyzer, achieving 95% accuracy in identifying CI failures and reducing manual triaging by 70%. Worked with cross-functional teams to design scalable preprocessing pipelines using Python, regex, and Jenkins to clean and standardize raw log data for feeding it to the log analyzer model.Automated 50+ regression and feature verification workflows with Selenium + Python, cutting manual QA effort by 60%. Optimized CI pipelines by refining automation scripts, improving pass rates from 83% → 97%. Supported continuous integration/continuous deployment (CI/CD) processes by analyzing test results from mainline to ensure existing functionality and verified quality metrics using Jenkins.
