Summary
👤
Senior🎓
Top SchoolJiun-hao Jhan is a machine learning engineer with eight years of experience bridging academic research and production ML, currently working at Apple after an MS in Software Engineering from Carnegie Mellon and prior MS work in data science at NTU. He has led teams and shipped multilingual NLP systems—most notably a prototype that extended Samsung Bixby to 51 languages and a published EMNLP workshop system that improved intent and slot accuracy by 15–25%. His work spans fine-tuning and optimizing LLMs (Dolly, GPT-J) using LoRA to cut trainable parameters dramatically, prompt engineering for automated annotation that reduced annotation costs by 80%, and practical deployment on AWS. Jiun-hao also has strong software engineering chops from MediaTek where he automated modem testing to save 60% of human resources, and a track record of top-conference NLP publications (NAACL, NeurIPS workshops). He combines hands-on coding in Python, C/C++, JavaScript and frameworks like PyTorch and HuggingFace with leadership in cross-disciplinary industry-academia projects. Colleagues can expect a pragmatic ML engineer who routinely turns research insights into measurable product impact.
