I validate AI conversational systems and build reliable automated quality assurance frameworks.
IndonesiaWhat I'm looking for
At Buat AI Mengantar, I validate LLM-powered conversational agents, design complex test scenarios, and work with prompt engineers to reduce hallucinated responses by 40%+.
Previously at Mamikos, I migrated automation from Selenium to Playwright, improving execution speed by 60% and reducing test flakiness by 45%. I built and maintained 150+ automated web test scripts, collaborated with developers to cut defect resolution time from five days to two, and mentored junior QA engineers.
I also bring experience from Campaign.com across web and mobile testing, performance testing, UAT, and cross-device UI/UX validation. I focus on practical QA practices for AI behavior, conversational flows, regression stability, and scalable automation.
