Syed Zubair A.

Senior QA Automation Engineer testing AI agents, LLM apps and SaaS platforms: Playwright, Selenium, Cypress, API, performance (JMeter/k6) and penetration testing. 11+ years, 12,000+ hours, on Upwork at 100% Job Success, ISTQB certified. WHERE I USUALLY GET CALLED IN - Your automation suite is flaky, slow, or nobody trusts it any more - You are shipping weekly with no regression safety net - An API or third party integration keeps breaking silently in production - You are about to launch and need an independent set of eyes before it goes live - You built an AI agent, chatbot or LLM feature and have no idea how to test something non-deterministic HOW I WORK I own the test strategy as well as the execution. Risk-based test planning, coverage design, and automation architecture that scales with your release cadence. I start with a risk map: what breaks, what it costs you when it breaks, and where coverage actually pays for itself. Then I build the smallest suite that protects those paths, wire it into CI, and hand it over documented so your team can extend it without me. SERVICES 1. Test Automation Frameworks Playwright (TypeScript/JavaScript), Selenium and Cypress. End-to-end, regression and cross browser suites built as maintainable frameworks, not scripts. CI/CD integration with GitHub Actions, Jenkins and Azure DevOps. Parallel execution and flake reduction. 2. AI Agent, Chatbot & LLM Testing Testing systems that don't give the same answer twice: AI agents, chatbots and voice agents. Golden dataset regression suites, LLM evaluation (LLM as judge), RAG retrieval accuracy, agent tool call checks, hallucination tracking, and prompt-injection testing mapped to the OWASP LLM Top 10. 3. Manual & Exploratory Testing Structured manual testing where automation doesn't pay: exploratory sessions, UAT, test cases and test plans, cross browser and device coverage with BrowserStack, and bug reports in Jira or TestRail a developer can reproduce on the first read. 4. API & Integration Testing REST, SOAP and GraphQL testing with Postman and code based suites. Auth and permission validation, webhook and third party integration coverage, database verification with SQL. 5. Performance & Load Testing JMeter and k6. Load, stress and soak testing with capacity findings written for engineers and for the people who sign the budget. 6. Security & Penetration Testing Web, Mobile, Infra and API penetration testing against the OWASP Top 10: authentication, access control, IDOR and business logic flaws. Vulnerability assessment with remediation guidance engineers can act on. Recent work includes fintech platform pen tests here on Upwork. 7. Mobile App Testing iOS and Android, native and hybrid: Appium automation, real device checks, and release readiness passes before App Store and Play Store submissions. 8. Accessibility & Compliance Testing WCAG 2.1 and 2.2 AA audits against EN 301 549, VPAT and ACR authoring, automated with Playwright ARIA snapshots so accessibility runs on every build. 9. AI Agent & Workflow Automation Builds AI lead-response and voice agents built on GoHighLevel(GHL), Vapi, Twilio, Lindy, n8n, Make and Zapier: lead capture, qualification, booking and follow-up. Every workflow is tested like software before handover, so leads don't drop silently. WHERE I HAVE DONE THIS I have led QA on platforms including EmpowerID, Bykea, CodeGen, Micro1, VistaJet and Careem - fintech, travel technology and ride hailing, where a bad release costs money or breaks compliance. Alongside that I take direct client work here on Upwork across e-commerce, healthcare and AI products. Regulated work is normal for me. I have tested identity and access management, payments and healthcare workflows where an audit trail matters as much as a passing test. WHAT YOU GET A test suite your team will still be running in a year. Bug reports a developer can reproduce on the first read. Clear reporting on coverage, risk and what I would fix next. No hand holding required. Available for short engagements and ongoing QA partnerships. Send me a message with what you are building and what is breaking, and I will tell you honestly whether I am the right fit.
