Hi, I am Anuj.

When I am not working on Google's Networking Team as an SRE, very often you will find me trying to think "I wonder if Nix can do this" which turns into a weekend project.

My talk is about 3 of those weekends.

Arik Grahl is a Staff Software Systems Architect living between Berlin and Barcelona and has more than 15 years of experience in full-stack development and operation of infrastructure on bare metal. At the moment he mainly designs cloud native systems and develops Golang applications close to Kubernetes. Furthermore, he is excited about everything evolving around Nix(OS) and enjoys contributing to Nixpkgs.

He studied computer science (BSc. in 2017, MSc. in 2021) at Technical University (TU) in Berlin. During this time he worked on freelance projects as a full-stack developer and supervised the corresponding IT infrastructure.
He also gained experience with co-founding two companies (2014, 2015) during this time with a focus on web development for small and medium-sized companies.

At his former job, he worked as a DevOps engineer where he also had the leading role in developing a mass-market product. He modernized and implemented operations and infrastructure at this company: containerization of all applications, an implementation of a CI/CD infrastructure, the operation of a self-hosted Kubernetes cluster on Bare Metal together with a Gluster and Ceph storage cluster in various locations in Europe, together with state-of-the-art observability stack. In addition, he was also intensively involved in the further training of employees concerning these technologies. Currently, he works as an Staff Software Systems Architect at SysEleven, where he is involved in the design of a cloud native software supply chain management on top of the managed Kubernetes and the development of Golang applications.

He is interested in IT security, data protection as well as network politics, and is an enthusiastic advocate of free and open-source software (FOSS). He is happy to take part in meetups and conferences to exchange ideas about technology. In his free time, he runs numerous services of everyday digital life on a home Kubernetes cluster, passionately cooks vegan food, does strength training, and listens to heavy metal.

Guillaume Maudoux (a.k.a @layus on GitHub and elsewhere) is an engineer and researcher specialized in build systems.

Based in Belgium, Guillaume blends a background in computer science, engineering, and applied mathematics with strong interests in correctness, reliability, and efficiency in software systems.

Guillaume works at Tweag’s Scalable Build Systems group. A team of engineers and researchers focused on developer productivity, robust tooling, and enterprise-scale build performance. His work focusses on integrating Nix into Bazel and in particular supporting remote execution. For some reason his skills are most appreciated in the robotics industry.

You may find him contributing to random open source projects because he never resists fixing a bug he found, and digging to uncover the root cause of problems. He will happily share his findings in blogs, conferences or around a coffeeC-w tea.

Guillaume’s reputation stems from his ability to bridge academic rigor with systems engineering pragmatism. His work helps teams build complex software more reliably, efficiently, and at scale.

I’m a software engineer advocate of Self Hosting and Data Sovereignty. I am specifically focused on how to improve long term maintainability of software and hardware. I work on SelfHostBlocks and Skarabox to lower the bar of entry to these domains.

I am also interested in distributed programming and declarative infrastructure as well as IoT electronics and smart home projects.

I am working at Wedo as a half Full Stack half DevOps Engineer. We work in Go and Typescript. I was previously working at Fastly on the Next-Gen Waf project, helping secure the web.

I’m the father of 6 wonderful children and married to a wonderful wife.
