About Me

Marco Jankowski

With a background in System Engineering and more than 25 years of experience in IT, especially Linux and Open Source, I have helped companies optimize and modernize their infrastructure and development processes.

From on-premises systems to cloud-native solutions, I've implemented and managed a wide range of IT environments and DevOps practices. My skills are focused on DevOps methodologies, automation, and Infrastructure as Code (IaC).

I work fluently with everything from cloud platforms, containerization, and configuration management tools to continuous integration and deployment pipelines. My expertise spans the entire IT operations spectrum, ensuring efficient, scalable, and reliable systems for organizations of all sizes.

Another key focus lies in debugging and troubleshooting complex systems. I have extensive experience in analyzing problems, identifying bottlenecks, and implementing solutions that improve system performance and reliability. My analytical approach and attention to detail enable me to identify and resolve even the most subtle issues.

Problem-solving skills and attention to detail
Clear, collaborative communication at eye level
Delivers on time, reproducible, maintainable – with focus on operational reliability
Quick to adopt new technologies with focus on thoughtful architecture design

Core Expertise

Kubernetes

Kubernetes

Experience in setup, scaling, and operation of hybrid cluster environments (cloud & on-premises), as well as developing, maintaining, and optimizing Helm charts for stable and maintainable deployments.

Infrastructure

Infrastructure Management

Experience in IaC and configuration management (Terraform, Ansible), hybrid and cloud infrastructures (Azure, AWS, VMware, bare metal), as well as designing scalable architectures, deployment automation, and optimization through reusability and modularization.

What Clients Say

It's my absolute pleasure to recommend Marco. I've had the privilege of working with him and have consistently been impressed by his profound knowledge and skills in DevOps and automation.

Marco's expertise was a cornerstone of our team's success. He skilfully leveraged tools like Ansible and Packer to engineer and automate the build of complex Open Virtualization Appliances (OVAs), which were deployed across various on-premise and cloud platforms.

In addition, Marco was a key architect in designing and implementing our replicated data storage solutions. His insights were key in deploying these systems seamlessly across both cloud and on-premise environments, especially within a complex Kubernetes context.

Beyond his technical talents, Marco is an exceptional team member. His great sense of humor and positive attitude made him a joy to have on the team. Marco would be a tremendous asset to any organisation, and he has my strongest endorsement.

Director

Global Technology Company

It's a real pleasure for me to recommend Marco. I had the opportunity to work with him on Avaya Hybrid Cloud (HCS) solutions, where he was a key counterpart in developing and bringing HCS to Azure Cloud.

Marco combines deep technical knowledge with strong practical skills, especially in Infrastructure as Code using Terraform and Ansible. His ability to automate and optimize complex environments was a huge asset to our work and made a real difference in delivering results.

Beyond the technical side, Marco is also a great colleague – clear in communication, easy to work with, and always positive. Working with him was both productive and enjoyable.

I can strongly recommend Marco to any team looking for an experienced and highly skilled professional in cloud automation and Kubernetes.

Cloud Solutions Architect

Avaya

I had the pleasure of working with Marco over the past year. He mentored my team and me on automation tools and Infrastructure as Code (IaC) methodology while we were developing and supporting Avaya solutions.

Marco isn't just brilliant, he's a true expert in his field. His technical skills are exceptional: he works with cloud platforms, containerization, OVA builds, CI/CD tools, Linux, and much more. He has a remarkable ability to step into complex, messy problems, debug them efficiently, and leave systems running better than before.

But the best part about Marco is his collaborative spirit. He's incredibly kind and generous when it comes to sharing knowledge. He didn't just fix issues for us; he stayed, often outside of regular hours, to mentor my team and ensure we truly understood the 'why' behind the fix. He always explained the pros and cons of each approach clearly, never rushed us, and maintained a consistently positive attitude.

Simply put, Marco is a top-tier engineer and a genuinely great human being. I highly recommend him, any team would be incredibly fortunate to have him.
