About

I have worked as a QA Analyst at TELUS Digital for 1 year. The QA tasks included, but not limited to, review and verify submitted emails meet project requirements, redact any personal, confidential and sensitive content, assign email threads to specific categories, label data, categorize data, and annotate data. Quality review tasks were conducted using an online Quality Assurance Tool. In addition, for Sundanese Language Annotator at TELUS Digital, I focused on not only reviewing the target language but also making sure that the content meet trust and safety. Last but not least, at micro1.ai, I have hands-on experience as an AI Training Expert for Indonesian Language project that required me to evaluate not only grader's response but also JSON output. Therefore, I believe my robust experiences will be beneficial for this Data Annotation project.
