Cloud native excellence, backed by top tier certifications
Curious about the expertise behind our Kubernetes services? Our engineers don't just have years of experience – they've also achieved the most challenging certifications in the cloud native world. Multiple TrueFullstaq team members are Kubestronauts: an exclusive title for professionals who have passed all five Kubernetes certifications from the Cloud Native Computing Foundation. This means you're working with engineers who know Kubernetes inside and out.
A Kubestronaut is someone who has achieved all five official Kubernetes certifications from the Cloud Native Computing Foundation: CKA, CKAD, CKS, KCNA, and KCSA. These aren't theoretical exams, but hands-on tests where you solve real Kubernetes challenges.
Only a small percentage of cloud-native professionals worldwide achieve this status. It requires not just technical knowledge but also practical experience with complex container environments. Our Kubestronauts understand how Kubernetes works and how to deploy it to solve real business problems.
At TrueFullstaq, we celebrate this achievement with something special: our Kubestronauts receive custom-made shoes as recognition of their expertise. And of course, they also receive the exclusive jacket from the CNCF.
Mastering Kubernetes goes beyond understanding technology: it's about understanding how organizations really work. Our Kubestronauts have proven they can handle the complexity of cloud-native architectures, from small applications to enterprise environments running thousands of containers.
This deep expertise means we don't build generic solutions, but Kubernetes environments that perfectly match your situation. Whether you want to migrate to containers, improve your CI/CD, or strengthen your security, our experts have the certifications and experience to help you move forward.
Igor de Beijer
"To me, Kubernetes is far more than container orchestration: a declarative way of working where changes are easy to track, setups are simple to reproduce, and battle-tested tools take the heavy lifting off my hands. That leaves me free to focus on what really matters: the result. Becoming a Kubestronaut is an exciting milestone, a great recognition, and a solid foundation to keep building on."
Rob de Jong
"Kubernetes is a complex world that's also changing fast. My challenge is translating that complexity and constant innovation into solutions that are practical and stable for the client. A common pitfall is carrying that complexity straight into the solution, while the real goal is to keep things as simple as possible."
Merijn Keppel
Lars Nieuwenhuizen
"In the cloud native world, Kubernetes currently plays a major role. Kubestronauts know how to integrate and automate Kubernetes within organizations, large or small. The expertise you need today is both deep and broad. That's why I want to keep developing as a DevOps Kubestronaut in the cloud native world, so I can better help my customers and colleagues."
Igor Nikolovski
"As a Kubestronaut, what I appreciate most about Kubernetes is its resilience—how it self-heals and keeps workloads running smoothly, even when things go sideways. I love the power of declarative configuration, where I can describe my desired state and let Kubernetes handle the rest. The automation is liberating; I spend less time babysitting deployments and more time focusing on what matters. And the isolation and resource control give me confidence that my workloads are running efficiently and won't step on each other's toes."
Cornelis Stuurman
"As a Cloud Native and DevOps Engineer, I enjoy diving deep into complex technical challenges to uncover the root cause and design effective, innovative solutions. I am passionate about continuously learning and exploring new tools, technologies, and concepts within the cloud-native ecosystem. A significant milestone in this journey was earning the prestigious Golden Kubestronaut certification, further demonstrating my expertise and commitment to the CNCF landscape"
Jorin Vermeulen
"As a Kubestronaut with extensive DevOps experience, I love diving into complex Kubernetes challenges. I'm always looking for ways to automate things. That's the foundation of every robust solution for me. The cloud native landscape keeps challenging me, helping me grow and build even better solutions."
Alexander Vreeswijk
"The cloud native landscape keeps evolving at a rapid pace, with Kubernetes long established as its central technology. In an ecosystem that's constantly changing, I find it important to move with it and keep discovering new developments. As a Kubestronaut, Kubernetes represents continuous learning and experimentation to me, and a way to keep deepening my knowledge of the broader cloud native landscape."
Thomas van Vugt
"The cloud native landscape is complex, but I believe in simple solutions for tough problems. I sometimes call myself a (K)YAML specialist with an eye for organization, but as a Kubestronaut, I provide extensive technical support and ensure alignment between people, processes, and technology for our clients."
Guillermo Wich
As a Cloud Native DevOps Engineer and Kubestronaut, I look beyond the details, getting to the core of complex challenges and helping teams stay focused on the end goal. By continuously learning and evolving within the CNCF ecosystem, I keep challenging myself and expanding my expertise.
While being a Kubestronaut is already exceptional, there's an even more exclusive level: Golden Kubestronaut. This lifetime achievement requires passing all 13 CNCF cloud native certifications plus the Linux Foundation Certified System Administrator (LFCS) exam.
Golden Kubestronauts receive special recognition, including an exclusive backpack, golden beanie, and lifetime benefits from the CNCF. It's the highest level of cloud-native expertise you can achieve—a true testament to mastering the entire ecosystem of cloud-native technologies, not just Kubernetes.
At TrueFullstaq, we're proud that our team includes professionals working toward this ultimate recognition, ensuring you have access to the deepest possible expertise in cloud native technology.
Certifications are nice, but what counts is what you do with them. Our Kubestronauts use their expertise to speed up your developers' work, make your infrastructure more reliable, and reduce your costs.
We believe in knowledge sharing. Our certified experts are happy to share their knowledge with your team so you can become more independent with Kubernetes. Because ultimately, it's not about impressing with certifications, but about helping your organization move forward with cloud native technology that actually works.
At TrueFullstaq, we value expertise and actively help our team members develop it. We support engineers on their journey to becoming Kubestronauts by providing study time, exam vouchers, and mentorship from our existing certified experts.
Whether you're just starting with Kubernetes or already have some certifications under your belt, we'll help you reach that Kubestronaut status. Our learning culture means you'll work alongside people who are passionate about cloud native technology and eager to share their knowledge. And yes, when you achieve all five certifications, those custom shoes will be waiting for you too.
