Computer scientist and full-stack developer specializing in AI model training and user-centered web apps.
United StatesWhat I'm looking for
I am a Master of Science in Computer Science with hands-on experience in full-stack development and AI model training. I focus on building accessible, scalable user interfaces and improving LLM performance through careful prompt design and evaluation.
In my AI work, I collaborate with engineering and product teams to refine conversational models, design personas, and produce evaluation reports that drive measurable improvements in coherence and user satisfaction. I apply bilingual fluency in English and Mandarin to ensure multilingual and cross-cultural relevance.
As a developer, I build single-page applications with React, TypeScript, Node.js, Express, and MongoDB, translating Figma designs into responsive, accessible UI and implementing secure APIs and payment flows. I emphasize code quality, clean architecture, and reusable components.
Earlier marketing and e-commerce experience informs my data-driven approach to product decisions, SEO, and user engagement. I combine technical craft with user empathy to deliver practical solutions that align with business goals.
