Judeyth Bui
AI Analyst & AI linguist
Bridging human language and machine intelligence. I specialize in high-fidelity prompt engineering and LLM fine-tuning for Healthcare and Tech
About me
Part Linguist, part AI Data Specialist, and 100% the person who touches the issues nobody else wants to. I turn linguistic chaos into structured intelligence for Healthcare and Tech. I am a polyglot and I like my prompts high-fidelity, my spreadsheets frozen, and my challenges ‘impossible’—because those are the only ones bother solving. Self-taught Spreadsheet Guru + UX Designer + Vibe-Coder. I turn ‘I don’t know’ into ‘I built it.’ Passionate about solving the problems no one else wants to touch and finding the perfect boba-to-ice ratio.
