Cindy Sridharan is a distributed systems engineer, O'Reilly author, and influential technical writer based in San Francisco. Known online as @copyconstruct, she wrote the seminal O'Reilly book 'Distributed Systems Observability' and runs the Systems Distributed newsletter on Substack. She is widely respected for her long-form thinking on observability, testing in production, microservices architecture, and engineering culture. She spent years as an engineer at imgix, led the Prometheus user group in San Francisco, and has spoken at major industry conferences including QCon and GOTO. Her Medium essays on monitoring, testing, and systems thinking have shaped how a generation of engineers thinks about building resilient software.
Gregor Hohpe is a transformation architect, prolific author, and sought-after speaker who has spent decades helping organizations bridge the gap between boardroom strategy and engine-room engineering. Co-author of the canonical 'Enterprise Integration Patterns' (2003), he coined the concept of the 'Architect Elevator' - the idea that great architects must fluently move between executive suites and server racks. A former Google Cloud Technical Director, Singapore Smart Nation Fellow, and Chief Architect at Allianz SE, Hohpe now runs the Architect Elevator platform, writing, teaching, and consulting on IT strategy, cloud, and the art of making everyone else in the room smarter.
Jon Gjengset is a principal engineer at Helsing, Rust systems programming educator, and author of 'Rust for Rustaceans' (No Starch Press). He holds a PhD from MIT CSAIL where he built Noria, a streaming dataflow database system offering up to 20x performance improvements. A prolific live-coder and YouTube educator since 2018, Jon co-founded ReadySet (a $29M-funded database startup), contributed to the Rust ecosystem, and teaches at MIT's Missing Semester. Based in Oslo, Norway, he is one of the most respected voices in the Rust community.
Kelsey Hightower is one of the most recognized figures in cloud-native computing - a self-taught engineer who rose from sleeping in his car to becoming a Distinguished Engineer (L9) at Google. Co-author of 'Kubernetes: Up and Running' and creator of the legendary 'Kubernetes The Hard Way' tutorial, he spent nearly a decade evangelizing Kubernetes and cloud-native practices before retiring from Google in 2023. Known for his disarming candor, human-first philosophy, and gift for making complex infrastructure accessible, Kelsey now serves as Board Director at Civo and continues to shape the future of platform engineering, AI, and open source sustainability.
Kris Nóva (1987-2023) was a principal engineer at GitHub, co-founder of The Nivenly Foundation, author, alpinist, and transgender activist who shaped the cloud-native infrastructure world. Best known for creating kubicorn, the Aurae runtime, and co-authoring Cloud Native Infrastructure with O'Reilly, she lived a life of radical generosity - growing Hachyderm from 700 to 40,000 users, founding the Privilege Escalation Foundation to support gender minorities in STEM, and writing Hacking Capitalism to help marginalized technologists navigate an industry that had once left her unhoused. She died on August 16, 2023, in a climbing accident in Seattle.
Laura Nolan is a Principal Engineer at Stanza Systems, a veteran Site Reliability Engineer, and one of tech's most credible voices on autonomous weapons ethics. After five years at Google - where she contributed to the seminal O'Reilly SRE book and resigned over Project Maven - and seven years at Slack as Senior Staff Engineer, she brings deep technical authority to both the reliability engineering world and the global debate over killer robots. Based in rural Ireland, she speaks at SREcon, QCon, and TED stages alike, writes the Responsible Computing newsletter on Substack, and holds seats on the USENIX Board and the SREcon Steering Committee.
Liz Fong-Jones is a Technical Fellow at Honeycomb.io, renowned SRE practitioner, co-author of 'Observability Engineering' (O'Reilly), and one of the most influential voices in the observability and platform engineering space. With 18+ years in software engineering spanning Google (11 years) and Honeycomb, she bridges deep technical expertise with fierce advocacy for labor rights, trans inclusion, and workplace equity. She led the Google Walkout Strike Fund in 2018, founded the Solidarity Fund by Coworker, and sits on the OpenTelemetry governance committee - all while speaking at every major SRE and DevOps conference on Earth.
Sam Newman is an independent consultant, author, and speaker who has spent over 25 years helping organisations navigate the messy realities of distributed systems. Best known for 'Building Microservices' - one of the most widely read technical books of its era - he runs Sam Newman and Associates from London, advising engineering teams worldwide on cloud architecture, microservices, and software resilience. A former ThoughtWorks principal, he is also the host of the Magpie Talk Show podcast and a sought-after conference speaker at events like QCon, NDC, and GOTO.
Theo Schlossnagle is a serial entrepreneur, software engineer, and investor who has spent three decades pushing the edges of distributed systems and scalable infrastructure. Founder of OmniTI (1997), Circonus (2010), and General Partner at L42 Ventures, he is a Distinguished Member of the ACM, an IEEE member, co-chair of ACM's Queue Magazine, and the author of 'Scalable Internet Architectures'. Beyond software, he runs a butcher shop in Maryland, maintains a farm retreat in West Virginia, and has left Twitter for greener (and more federated) social pastures.
Dilawar Mahmood is a machine learning engineer at ZeroEntropy (YC W25) in San Francisco, best known for four years at Apple where he optimized on-device models for Siri and Spotlight - work he once presented directly to Tim Cook at the Steve Jobs Theater. A Norwegian-educated engineer who left a comfortable career track to attend the Recurse Center and rediscover what programming actually feels like, he builds distributed ML frameworks in his spare time and is on record hating vibe coding.
Yao Fu (符尧) is an AI researcher at xAI specializing in large language model reasoning, efficient inference, and distributed systems. A PhD graduate of the University of Edinburgh, he previously worked at Google DeepMind on Gemini 3 and Project Astra. With over 5,000 citations and key papers like ServerlessLLM (OSDI '24) and DuoAttention (ICLR '25), Fu bridges systems engineering and ML research. He writes the 'Yao Fu' newsletter on Notion and is known for the Chain-of-Thought Hub benchmark repository, which helped track LLM reasoning progress across the field.
