Sr. QA Automation Engineer | Playwright Frameworks | AI‑Powered QA & LLM Agents | Web & API Testing

About

I’m a QA Automation Engineer specialising in Playwright frameworks, AI‑powered QA workflows, and project observability for complex web and API platforms. Over the last 5+ years, I’ve moved from classic test automation into building agents and harnesses that connect Gemini, Jira, Playwright, and Langfuse to make testing smarter, faster, and more repeatable. At OneOrigin, I design and own Playwright‑based test frameworks (POM + fixtures + CI) for products like Triangulator (a transfer‑credit suggestion engine backed by PostgreSQL/RDS, graph databases, and AWS services), and I mentor junior QA engineers while standardising test strategy, documentation, and risk‑based testing. On the AI side, I’ve built: qAgent – an AI QA agent that uses Gemini and Jira as RAG to manage tickets, generate test cases, create Playwright code, and file bugs, deployed on Vercel. Sentinel – a self‑learning, open‑source Playwright framework with a custom harness and observability layer. Observe – a unified Langfuse + OpenTelemetry + Next.js dashboard that shows LLM traces, Playwright steps, GitHub activity, Supabase run states, and deployment signals in one place. My stack includes Playwright (advanced), JavaScript/TypeScript, Python, Cypress, Selenium, Jira, GitHub Actions, Docker, Langfuse, OpenTelemetry, Gemini, n8n, Genkit, LM Studio, and local models via Ollama. I work in Agile teams, own QA outcomes end to end.
