SAP HANA DB & Analytics SAP Ariba Retail Tech Stack & Tools

As a senior technologist in AI-driven test automation and quality engineering at SAP, I have played a transformative role in building intelligent testing ecosystems powered by machine learning, generative AI, and DevOps automation. My contributions have significantly enhanced efficiency, reduced defect leakage, and accelerated release cycles for enterprise platforms such as SAP HANA and SAP Ariba Retail.

• ML-Based Test Recommendation System: Developed a machine learning model that predicts the most impacted tests based on incoming pull requests or code changes, thereby reducing test cycle time and focusing execution on risk-based areas.
• GenAI-Powered Test Impact Analyzer: Built a GenAI utility that analyzes test suites in real time to recommend affected test cases based on recent code commits, file diffs, and functional areas using embeddings and prompt engineering.
• Auto-Healing Test Automation Framework: Designed a GenAI-based tool that self-corrects broken locators at runtime by dynamically interpreting DOM changes, significantly reducing test flakiness.
• Natural Language to Test Step Generator: Created a prompt-driven LLM tool that converts plain English test cases into executable automation scripts using structured templates, accelerating test case authoring.
• AI-Driven Log Analyzer: Developed a tool that uses NLP and anomaly detection models to scan log files, and pinpoint root causes of failures across distributed systems.
• Test Copilot Chatbot: Implemented an internal chatbot powered by LLMs that assists testers by generating XPath/CSS locators, debugging automation issues, and explaining test failures using logs.
• Owned quality assurance for SAP HANA and SAP Analytics Cloud, focusing on integrating AI/ML-driven data insights into QA.
• Architected an enterprise-wide test automation framework for web, mobile, API, visual UI, performance, and security.
• Implemented AI-based tools for performance prediction, capacity forecasting, and dynamic load testing.
• Led quality efforts for SAP Ariba’s Retail Solution, focusing on procurement workflows, S4 integration, and contract automation.
• Developed reusable test components and custom web tools, and participated in several AI and DevOps Hackathons.
• Languages/Frameworks: Java, Python, TypeScript, Spring Boot, NodeJS, MEAN Stack, and Angular.
• Automation Tools: Selenium, Appium, Katalon, JMeter, Jasmine, Protractor, Applitools, ZAP Proxy, BurpSuite
• CI/CD & Ops: Jenkins, Git, Terraform, Chef, Docker
• AI/ML & GenAI: TensorFlow, scikit-learn, LangChain, Ollama, OpenAI API, Azure OpenAI, Sentence Transformers
• Platforms: SAP BTP, SAP HANA, SAP Analytics Cloud (SAC), Azure, Kafka
• Optimized performance through testing and tuning of applications.
• Designed updates to existing software to meet changing customer demands.

As Head of Quality – Cloud at Netradyne, I was responsible for overseeing the quality strategy and end-to-end validation of Driver•i—an AI-, Computer Vision–, and IoT-powered fleet safety platform. The system integrated smart in-vehicle devices with a cloud-based analytics engine to monitor real-time driver behavior and provide actionable safety insights.

I architected and led the development of a Cloud Integrated Test Automation Framework (Java + Python) to ensure seamless validation of data ingestion pipelines, cloud analytics, and REST APIs.
