Hamza Muhammad Khan is a Karachi-based DevOps and cloud engineer who climbed from supporting small-scale WordPress deployments to managing infrastructure at DigitalOcean as an Engineer II before moving into banking-sector DevOps at Bank Al Habib Limited. Educated at NED University (Master's in Computer Science, 2023) and the University of Karachi (Bachelor's in Computer Software Engineering, 2019), he specializes in Linux administration, Kubernetes, Docker, and cloud platform operations - and moonlights as a blockchain tinkerer and machine-learning experimenter on GitHub.
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.
Joe Beda is the co-creator of Kubernetes and Google Compute Engine, a software engineer who helped build the infrastructure layer that now underpins the modern cloud. After a decade at Google where he made the first Kubernetes commit on GitHub, he co-founded Heptio to commercialize Kubernetes adoption, which VMware acquired in 2018 for roughly $550 million. Now semi-retired, he advises companies like Tailscale, invests in startups including Bluesky and Edera, and writes about technology at eightypercent.net - a blog named after his belief that a simpler system solving 80% of the problem beats an overengineered one that never ships.
Justin Garrison is a platform engineering veteran who helped launch Disney+ from zero to 50 million subscribers, spent 3.5+ years as a Senior Developer Advocate at AWS working on EKS, and now serves as Head of Product at Sidero Labs. He co-authored 'Cloud Native Infrastructure' with O'Reilly, hosts the Ship It! and Fork Around and Find Out podcasts, and is one of the original chairs of the Kubernetes SIG on-prem. He's known for critical, no-hype takes on cloud native trends and a deep commitment to open source 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.
Xe Iaso is a technical educator, open source founder, conference speaker, Twitch streamer, and VTuber based in Ottawa, Canada. The CEO of Techaro and creator of Anubis - the open-source anti-AI-scraper tool now protecting GNOME, FFmpeg, Linux kernel archives, and UNESCO - Xe built a cult following of 400+ blog posts that mix deep systems engineering with irreverent philosophy. Known for pioneering developer relations teams at Tailscale and Fly.io, and for coining their own title 'Archmage of Infrastructure,' Xe is the rare technologist who turned shitposting into a career strategy and made it work.
Yevgeniy 'Jim' Brikman is the co-founder of Gruntwork and one of the most influential voices in infrastructure-as-code. Author of three O'Reilly books — 'Terraform: Up & Running' (now in its 3rd edition), 'Hello, Startup', and 'Fundamentals of DevOps and Software Delivery' (2025) — he has spent 15+ years building infrastructure that served hundreds of millions of users at LinkedIn, TripAdvisor, Cisco Systems, and Thomson Financial. At Gruntwork, he helped pioneer the idea of treating infrastructure like software: testable, reusable, and versioned.
DigitalOcean is a cloud computing platform designed for developers, startups, and SMBs, offering simple, predictable pricing and powerful infrastructure from virtual machines to high-performance GPU instances.
