AI Agent QA Engineer | LangChain | Python | Selenium | Test Automation

Looking to build or test AI-powered applications? I specialize in AI Agent testing and QA automation — combining hands-on LangChain/Python AI development experience with deep test automation expertise to validate intelligent systems end-to-end. At BIGO Technology, I built an AI-Agent autonomous testing platform using Python, Claude API, and LangChain — enabling intelligent log analysis, automated defect classification, and self-healing test workflows. This is not just QA theory: I have designed and shipped production AI testing infrastructure serving millions of users. My automation stack covers the full spectrum: Selenium and Appium for web and mobile UI testing, Java-based test frameworks, API testing (REST/RPC/Postman), CI/CD pipeline integration (Jenkins/GitHub Actions), and performance testing. At BIGO, I architected end-to-end test platforms covering 500+ test cases across Android and iOS, cutting regression cycles by 70% and enabling continuous delivery for high-concurrency apps. What sets me apart: I bring a rare combination of AI Agent development experience and enterprise-grade QA automation — I understand how LLM-based systems fail, how to design prompt adversarial tests, validate RAG pipelines, and build reliable regression coverage for AI workflows. Based in Abu Dhabi (UTC+4), available for Asian and European business hours. Whether you need AI Agent testing strategy, LangChain workflow validation, Selenium/Appium automation framework setup, or CI/CD test pipeline integration — I deliver production-grade results. Let's discuss your AI testing needs — message me and I typically respond within a few hours.
