Summary
👤
Senior🎓
Top SchoolRezka Leonandya is a Lead Data Scientist with 11 years’ experience building production ML and data pipelines, currently leading Routing & Maps at GoTo Group. She blends deep NLP and deep learning research (including academic publications) with hands-on engineering—maintaining ~200 daily production pipelines and shipping real-time ETA, route-similarity, and maps error-detection systems that materially improved metrics and automated workflows. Her background spans product-facing analytics, feature engineering, graph-aware ML, and deployment of low-latency models, plus prior roles improving search, recommendation, and chatbot automation. Trained in AI and computational linguistics at top European institutions, she’s equally comfortable publishing research and optimizing engineering trade-offs in production. A pragmatic googler and rapid learner, Rezka often turns complex, noisy location and text signals into scalable, high-precision solutions.
