Summary
👤
Senior🎓
Top SchoolJohnathan Nguyen is a Senior Lead Machine Learning Engineer based in Paris with 10 years of experience building production-grade ML systems and platforms. At DreamQuark he architects Kubernetes- and Ray-based platforms that serve diverse models from recommendation engines to LLMs, and led a Next Best Action engine comprising 40+ specialized models for personalized investment products. He combines hands-on model work (PyTorch, Roberta/CamemBert, LightFM) with robust MLOps—MLflow, DVC, Prometheus, Grafana—and has engineered scalable data preparation and orchestration layers using Pandas/Dask and microservices. Previously a co-founder and CTO at a consumer startup, he brings full-stack engineering and cloud deployment experience (AWS, Spark/EMR) alongside product and SEO sensibilities. His background in applied math/data science and a habit of weekly “sidequests” like Kaggle projects reflect a continuous-learning drive that informs both research-grade models and reliable production delivery.
