Freelancer Overview

I am a professional in IT with extensive experience in Quality Assurance (QA) for various clients across different software, including mobile apps, web-based apps, and LLMs. I specialize in functional, UX/UI, and localization testing, prompt and response authoring, data labeling, and data validation. I am skilled at translating and verifying content, ensuring cultural and contextual accuracy. I am adept at mastering new methods quickly and coordinating with diverse stakeholders and teams. I am passionate about human language and intercultural communication. My background in communication and discourse analysis equips me with advanced analytical skills, providing a strong foundation for addressing the complexities of training and optimizing LLMs. I am interested in contributing to developing technologies that can improve human-machine communication.
