Originally a Unix/C engineer, she moved to Java over two decades ago and focuses on multi-agent systems and real-time data workflows. She explores how developers can adopt modern data pipelines. Her talk on [event messaging with Apache Pulsar](/videos/538-event-messaging-and-streaming-with-apache-pulsar) unpacks cloud-native scaling, while her session on [understanding vector search](/videos/844-enter-the-brave-new-world-of-genai-with-vector-search) details how to mitigate data staleness using RAG. On the community side, Mary runs the local Chicago Java Users Group. ## Past Sessions ### World Congress 2026 Europe - Virtual Stage · June 30, 2026 Online - [Building Scalable Multi-Agentic AI Systems in Java: Orchestrating Agents with Event-Driven Approach](https://www.wearedevelopers.com/events/world-congress-2026-europe-virtual-stage/sessions/1508-building-scalable) ## WeAreDevelopers LIVE - [Enter the Brave New World of GenAI with Vector Search](https://www.wearedevelopers.com/videos/844-enter-the-brave-new-world-of-genai-with-vector-search) · Mary Grygleski - [Event Messaging and Streaming with Apache Pulsar](https://www.wearedevelopers.com/videos/538-event-messaging-and-streaming-with-apache-pulsar) · Mary Grygleski ## Links - [X](https://twitter.com/mgrygles) - [LinkedIn](https://www.linkedin.com/in/mary-grygleski/) - [Blog](https://dev.to/mgrygles)
