Jorge O. Castro is a community manager, specializing in Open Source. He’s basically a cat herder – a combination of engineering, developer relations, and user advocacy.


Starting as a system administrator at Oakland University in Rochester Hills, Michigan, Jorge joined Canonical to work on Ubuntu for about 10 years before moving to Heptio to work on Kubernetes. Heptio was then acquired by VMware in December 2018 where he learned about Enterprise software (oh boy!). Then he did a tour at Stacklet working on the Cloud Custodian project, saving you some dollar bills. These days Jorge is a Developer Advocate at the Cloud Native Computing Foundation, where he’s tasked with helping make open source sustainable.

Principal Research Software Engineer (Generative AI)

Microsoft logo
Read More

I am currently a Principal Research Software Engineer at the Human-AI eXperiences (HAX) team, Microsoft Research where I focus on Generative AI. My research interests are at the intersection of human-computer interaction (HCI), computational social science, and applied machine learning. My research has been published at conferences such as ACL, EMNLP, AAAI, and CHI and has received multiple best paper awards. My work has also been featured in outlets such as the Wall Street Journal and VentureBeat. I am an IEEE Senior member, a Google Certified Professional (Data Engineer, Cloud Architect) and currently a Google Developer Expert in Machine Learning.


I Hold a PhD in Information Systems from City University of Hong Kong (recipient of the HKPFS scholar award by the Hong Kong Research Grants Council). My dissertation studied developer contribution behaviour in software crowdsourcing contests – factors influencing participation, the impact of incentives on participation behaviour and the problem solving process within crowdsourcing contests. Prior to City University, I studied at the Information Networking Institute at Carnegie Mellon University where I earned a Masters degree in Information Networking. I previously worked as a Principal Research Engineer at Cloudera Fast Forward Labs, Research Staff Member at IBM Research, Technical Lead for MIT Global Startup Labs, Researcher at the Innovation Management Lab, Athens Information Technology Athens Greece, and founder/lead developer for a small startup focused on West African markets.


In my free time, I enjoy music (some self taught guitar, piano), sports (participated in the Hong Kong Marathon thrice) and exploring art (some drawing, 3d modelling, african mask art).

Chairman & CEO

DataStax logo
Read More

Chet Kapoor is Chairman and CEO of DataStax, the real-time AI company. With more than two decades of leadership across tech giants like Google, IBM, and BEA Systems, Chet has always thought about infusing AI into businesses at scale. With his roots at Steve Jobs’ company NeXT, Chet learned the power of working with incredible people who want to change the world. This insight helped fuel his career and he ultimately took the helm of Apigee as CEO in 2007 where he saw APIs as a platform for bringing AI to the enterprise.


After a successful IPO and eventual acquisition of Apigee by Google, Chet dug in and recognized the solution to deeply enabling AI at scale was to start with data. His journey culminated when he became the CEO of DataStax in October 2019. With a focus on strategy, operations, and people, the company launched Astra DB—a pioneering DBaaS powered by Apache Cassandra—and seamlessly integrated real-time AI with streaming capabilities and event processing engine, Kaskada’s, feature store. Now, with vector search for generative AI, DataStax customers can build massively scalable AI agents and deliver powerful apps leveraging generative AI.
