Summary
👤
Senior🎓
Top SchoolHao-xuan Wang is a Senior Data Scientist with a decade of experience building production ML systems focused on ASR, LLMs, and safety-critical audio applications across companies like Zoom and Grab. He combines research-led improvements (notably in LLM-augmented ASR and rare-word recognition) with end-to-end engineering — from model training and evaluation to deployment and service ownership. Recent work uses audio keyword spotting and speech LLMs to proactively protect passenger and driver safety, and a short-term project achieved an 87% F1 for question-intent detection from partial ASR outputs. Comfortable in distributed pipelines (Spark, DJL) and transformer fine-tuning, he also has experience in entity linking, transaction-graph analysis, and active learning. Based in Hangzhou with roots across Europe and Asia, he’s open to remote roles in London, Tokyo, Ireland, and Singapore and aspires to a digital-nomad lifestyle. Actions speak louder than words — his GitHub and blog document a pragmatic, results-oriented approach to applied NLP.
