I played a pivotal role in enhancing QA automation at Salesforce through cutting-edge AI technologies. 1. Autonomous AI QA: Architected a fully autonomous multi-agent QA system that uses Playwright CLI to read PRDs, generate and execute tests, and auto-file bugs with zero human intervention. 2. GenAI Test Generation: Created an Agentic AI RAG solution to automatically generate functional and E2E tests directly from technical spec documents. 3. LLM Evaluation: Built a RAGAS pytest framework to assert RAG-based LLM metrics and enhanced Jest frameworks for data-fidelity testing. 4. Data Setup Agents: Developed a test-data-setup agent integrating an LLM Gateway with the Salesforce CLI to automate data creation for automation orgs.

About

I am a Senior SDET, Test Automation Architect, and AI SDET dedicated to transforming quality engineering through artificial intelligence and robust automation strategies. Throughout my career at companies like Salesforce, Gojek, and Paytm, I have specialized in building highly scalable testing frameworks from the ground up and implementing left-shift strategies that drive developer productivity. Currently, as Senior Member Technical Staff at Salesforce, I am pioneering the integration of LLMs and Agentic AI into the QA lifecycle. I thrive on solving complex engineering problems, whether it is architecting fully autonomous multi-agent QA systems or engineering reliable E2E backend automation for high-scale microservices.
