@joshuagunawan
I improve AI systems through multilingual annotation, evaluation, and quality assurance.
United StatesWhat I'm looking for
I've evaluated and labeled production AI data for LinkedIn’s job-search AI and Meta’s Llama models, including 27,000+ text, image, audio, and user-prompt records at 95%+ accuracy. I use RLHF preference ranking, LLM output evaluation, content-safety labeling, and rubric-based scoring to improve relevance, quality, and policy alignment.
At Trimble, I translated stakeholder input into feature requirements and UI mockups adopted by 800+ companies, while reducing mid-sprint engineering roadblocks by 33%. I also bring data science and business intelligence experience, plus native English and Indonesian and work-proficient Mandarin.
