🏆 ISTQB-Certified | 14+ Years | 10,000+ Bugs Found | 1,000+ Automated Tests | 100+ Apps Healthcare & AI/LLM QA Engineer. I test the apps where one bug means a missed diagnosis, a HIPAA gap, or an AI model giving a patient the wrong answer. I help healthcare, HealthTech, and AI teams ship safely, including LLM apps, RAG pipelines, and AI agents. 📌 RECENT WORK - MMT (Kelvin): AI video analysis for Parkinson's motor assessments on web, iOS, and Android. 200+ bugs found, Playwright and Appium automation saved 40% of test effort, HIPAA compliance achieved. - CliniScripts: AI medical scribe. Validated transcription accuracy, offline-to-online session sync, and EMR data mapping. - TestComet: LLM-generated test cases run by AI agents. Tested RAG grounding, hallucinations, and agent reliability, with 300+ bugs reported. - YOU(th) Health, OMED Health, HWA, Lume Health: smartphone health checks, device-connected gut-health tracking, a three-portal telehealth platform with Zoom sessions, and circadian light tracking. 🤖 AI & LLM TESTING - Hallucination, grounding, and answer-accuracy checks for RAG pipelines - Prompt injection, jailbreak, and guardrail testing - Multi-turn context, memory, and AI agent tool-use validation - Eval suites in Promptfoo and DeepEval, run in CI/CD - Regression baselines for non-deterministic AI output 🏥 HEALTHCARE & HEALTHTECH TESTING - Patient-facing apps, telehealth, and remote patient monitoring - MedTech companion apps and device-to-app data sync - EMR/EHR integrations and clinical documentation workflows - PHI handling, role-based access, and audit-trail checks (HIPAA-aware) - Real-device testing on Android and iOS ⚙️ CORE QA & AUTOMATION - Web automation: Playwright, Cypress, Selenium - Mobile automation: Appium, Maestro - API testing: Postman, Rest Assured - Performance: JMeter, LoadRunner (HP Accredited) - CI/CD: GitHub Actions, CircleCI, with Allure and Slack reporting - Manual, exploratory, regression, and cross-browser testing 🚨 WHEN TEAMS BRING ME IN - Your AI feature gives different answers to the same question - Data looks right on web but breaks on mobile, or after a sync - You're weeks from launch or a compliance review with thin test coverage - Regression takes days and still lets bugs through ⭐ WHAT A CLIENT SAID "Within one month, user complaints dropped by 30%. He implemented automation, integrated CI/CD, reduced manual testing by 50%, and saved 10+ development hours per sprint." 🤝 HOW I WORK In week one I map your riskiest flows and agree a test plan. Test cases live in your tool (Jira, X-Ray, Azure DevOps). Every bug comes with steps, severity, and a video. Before each release you get a clear go/no-go. Available 30+ hrs/week, with overlap for US, UK, EU, and Australian hours. 👉 Send me your app and the release date you're worried about, and I'll tell you where I'd look first.
