Summary
👤
Senior🎓
Top SchoolOfri Kleinfeld is a Senior Machine Learning Engineer based in Tel Aviv with 9 years of experience building production-grade AI and big data systems across Booking.com, Microsoft, and PayPal. He specializes in moving models from research to production—optimizing GPU inference, automating CI/CD for SageMaker, and deploying low-latency ML enrichment in stream and batch pipelines using Flink and Spark. He regularly combines foundation-model work, RAG with OpenSearch, and custom MCP tools to extend agent capabilities and integrate third-party APIs. Comfortable across AWS, Azure, Kubernetes and Terraform, he pairs strong software engineering (Java, Dropwizard) with data-science rigor from an MS in Computer Science. A less obvious strength is his background in security and fraud detection, which informs robust, signal-driven anomaly detection and improves model signal-to-noise in production.
