IndonesiaWhat I'm looking for
I am a QA Engineer with almost three years of hands-on experience in product and implementation QA, currently specializing in data quality for Data & AI systems. I validate SQL transformations, ETL pipelines, and data outputs while ensuring business workflows and system integrations align into reliable, scalable solutions.
I have reduced processing time by 60% through early defect detection and improved validation workflows, and I delivered 95% of assigned QA tasks on schedule while supporting UAT, deployment validation, and post-release data verification.
I contribute across the SDLC using manual and automated testing (Selenium, RestAssured, Appium), API testing with Postman, and collaborate with Data Engineers on pipeline issues and ML pipeline validation to ensure dataset integrity, feature outputs, and model inference sanity.
