QA Engineer with more than 5 years of experience testing enterprise systems, from payment processing platforms to mobile e-commerce apps and AI-integrated applications. I've played a central role testing a revenue-critical payment processing system, covering the full SDLC test lifecycle within Agile/Scrum teams and maintaining a near-zero post-production defect rate across 500+ test cases spanning smoke, sanity, regression, and UAT.
My background covers manual and API testing (Postman, SoapUI, Swagger), test management in JIRA, Zephyr, and TestRail, and validating complex integrations across Salesforce and Dell Boomi. I've caught production-critical bugs before they shipped, including a fee-mapping defect that would have hit live client transactions, and I document everything clearly enough that developers never need a follow-up call to reproduce an issue.
I've also worked on independent projects testing AI-integrated apps and AI agents — evaluating output accuracy, hallucination rate, prompt handling, and guardrail behavior alongside standard functional and API testing.
Earlier in my career I tested mobile apps (iOS/Android) and payment flows, and ran API and regression testing for global clients. I work well async and across time zones, and I'm looking for remote QA roles - contract or full-time - where thorough testing and clear communication actually move the needle.
