Senior QA Automation Engineer | SaaS, API & AI/LLM Test Automation

Stop shipping bugs to production. If your SaaS or AI product is scaling fast, manual QA and fragile test scripts will slow you down—and cost you users. I help teams build robust, scalable test automation systems that catch critical issues early, so you can release faster with confidence. 🧠 What I Actually Do (Beyond "Testing") Most QA engineers execute test cases. I design test architectures that: • Scale with your product • Reduce manual QA dependency • Integrate seamlessly into CI/CD pipelines • Prevent regressions before they impact users ⚙️ How I Help SaaS & AI Teams ✔ Build automation frameworks from scratch (Python / Java) ✔ Stabilize flaky test suites killing your release cycles ✔ Implement reliable UI + API automation ✔ Integrate testing into CI/CD (Jenkins, GitHub Actions, Azure DevOps) ✔ Validate AI/LLM outputs for accuracy, consistency & edge cases — including building automated evaluation frameworks (e.g. RAGAS) for LLM-powered products 📈 Real Business Impact • Reduced critical production defects by 40% for a healthcare SaaS platform • Achieved 90%+ automated test coverage across multiple products • Cut regression testing time by 35%, accelerating release cycles • Maintained 100% Job Success Score with consistent 5⭐ client feedback 🧩 Projects I'm Best Fit For • Scaling SaaS platforms needing reliable automation • AI/LLM products requiring validation & evaluation frameworks • Teams struggling with flaky tests or slow releases • Startups preparing for rapid growth or funding stages ⚡ My Approach • Think like a product owner, not just a tester • Focus on risk-based testing, not unnecessary coverage • Build systems your team can actually maintain long-term 🤝 Let's Work Together If you're releasing features fast but worried about quality, spending too much time on manual QA, or dealing with unstable automation — I can help you fix that. 👉 Send me an invite with a quick overview of your product, and I'll suggest the best testing approach for your setup.
