Huy Nguyen is a Senior Data Engineer with nine years' experience building large-scale data and ML systems across finance and hiring platforms, currently at Qube Research & Technologies in Hong Kong. He combines strong engineering skills in Java, Scala, Python and TypeScript with deep AWS expertise (S3, EMR, Lambda, Athena, Fargate) and production data tooling like Spark, Databricks and Metaflow. At SEEK he shrank ML retraining from weeks to hours, built a sub-50ms recommendation engine across 50M profiles, and productionised ranking models that measurably improved hiring outcomes. Comfortable spanning ML, NLP (spaCy, TensorFlow) and platform engineering, he also drives developer productivity through shared Python ecosystems and CLI tooling. A pragmatic problem-solver with a security-aware mindset (cybersecurity background and TDD/clean-code practices), he excels at turning complex data flows into reliable, low-latency services.
