About

I’m a results-driven QA professional with 9+ years of experience leading end-to-end test automation strategies across AI, SaaS, and high-scale tech platforms. Currently at Writesonic, I lead the QA efforts for AI writing tools powered by OpenAI (GPT-4, RAG-based architectures), driving 99% accuracy and 30% faster CI/CD test cycles. My expertise lies in building scalable automation frameworks (API/UI/backend) using Python, Playwright, and Selenium; optimizing performance with tools like Locust and JMeter; and integrating QA into CI/CD pipelines via Jenkins, GitHub Actions, and Docker. I’ve also contributed to OpenAI evals and testing of LLM APIs under real-time data workloads. I bring deep experience working with global teams, mentoring QA engineers, and aligning quality practices with business goals. My work consistently enhances test coverage, system reliability, and product stability across fast-paced environments. Core Skills: OpenAI QA | RAG Evaluation | Python | Playwright | Selenium | API Testing | Test Automation | GitHub Actions | Jenkins | Docker | DevOps QA | CI/CD Pipelines | AI/ML QA | LLM Testing | Performance Testing | Cloud QA (AWS/GCP) I'm passionate about enabling teams to ship faster and with confidence—by embedding quality early, automating intelligently, and continuously evolving testing strategies. Let’s connect if you’re building cutting-edge AI products and need someone who can own quality across the stack, from backend APIs to AI evaluations.
