Case Studies & Testimonials
Rebuilding KubernetesInfrastructure for a WebAgency
This two-year gradual migration involved moving from a custom Kubernetes solution to AWS EKS. I redesigned deployment strategies to reduce deployment time from hours to minutes, migrated PostgreSQL databases to managed Aurora or operator-based solutions, and transitioned Prometheus monitoring to Mimir and Loki. Additionally, I implemented complex egress strategies with Istio and Cilium to ensure secure and reliable egress networking.

Containerizationfor a largeFinTech Company
I led the Dockerization and Kubernetes adoption process, delivering hands-on workshops for developers. The result was a custom on-premises Kubernetes platform tailored to their legacy infrastructure, significantly improving scalability and developer autonomy.

Infrastructure fora RAG Chatbot
Designed and deployed a Kubernetes-based infrastructure for a Retrieval-Augmented Generation (RAG) chatbot. This system leveraged Azure OpenAI models for vectorization and inference, providing a scalable and cost-efficient deployment environment.

"I worked with Mario on building a custom UI framework and co-founding a frontend meetup community. Even in frontend work, he always brought an engineering mindset that went far beyond the UI — thinking about tooling, automation, and how to scale ideas efficiently. His ability to connect architecture with developer experience made him a natural fit for DevOps thinking before we even called it that."

Engineering Manager at Outreach
"Mario was my tutor and wingman during our Kubernetes project at EmbedIT. His technical expertise and out-of-the-box thinking made a real impact. On top of that, his team spirit makes him a great person to work with. Highly recommended."
"I collaborated with Mario on revitalizing clusters in a hybrid environment. I greatly appreciated his focus on clean solutions, proactive attitude, and ability to work independently. Throughout the project, the continuous sharing of information and our cooperative approach allowed us to refine our process and achieve a cohesive outcome. The resulting clusters are fully functional and thoroughly documented. I can wholeheartedly recommend Mario—not only for his technical expertise but also for his excellent communication skills."

BOOK A CALLAbout Me
I'm Mario Vejlupek — DevOps consultant,
former developer, meetup founder, and speaker.
former developer, meetup founder, and speaker.
With over 20 years of hands-on experience in tech, I’ve supported companies across continents in building fast, secure, and scalable infrastructure — from lean startups to large distributed enterprises.
I’ve trained more than 100 engineers in Kubernetes fundamentals, led DevOps transitions from legacy systems to modern infrastructure, and helped cross-functional teams work better together through smarter tooling and clearer communication. I also founded the ngParty meetup group, which has grown into a space for developers and operations folks to learn and share.
Beyond work, I bring tech to classrooms — teaching kids programming, robotics, and problem-solving using LEGO and Minecraft, and creative challenges. Helping the next generation understand how things work is deeply rewarding and keeps my own curiosity sharp.
My philosophy is simple: build infrastructure that gets out of the way. Automate what’s boring. Share what you learn. And never lose sight of the human side of tech.
I believe in making complex systems
understandable, usable, and empowering— whether you're a startup
or an enterprise.
