About

I am an AI product specialist with over 4 years of experience spanning AI evaluation, technical support, and product operations. Most recently at RWS Group, I have contributed to RLHF pipelines and multimodal LLM evaluation while also leading developer communities and managing technical support operations. My work spans RLHF evaluation, prompt engineering, and AI product support using tools like Claude API, Gemini API, Flutter, Firebase, and Python. I have built and shipped commercial apps with Flutter and Firebase, developed AI habit coaches, and created analytics tools using Python, pandas, and SQL to track annotation quality and productivity.
