Dominik Walczyna
DevOps Engineer & Cloud Architect · Founder, QuackStack Technologies
I design, automate, and secure cloud infrastructure - turning fragile deployments into resilient, self-service platforms on AWS, Azure, and GCP.
01About
I'm a DevOps Engineer and Cloud Architect with over eight years of experience designing and running production infrastructure across AWS, Azure, and GCP. I hold a degree in Automation and Robotics from the Warsaw University of Technology, and founded QuackStack Technologies to bring that same cloud-native philosophy to more teams: automate everything, observe everything, and give engineers a platform they can trust.
My work spans Kubernetes platform engineering, GitOps delivery pipelines, service mesh architecture, and observability - turning fragile deployments into resilient, self-service systems, with security built in from day one rather than bolted on afterward.

03Cloud-Native Approach
The engineering principles behind every platform I build.
Cloud-Native Infrastructure
Kubernetes, containers, and service mesh architecture across AWS, Azure, and GCP - built to scale horizontally and recover automatically.
Infrastructure as Code
Every environment defined in Terraform and Ansible, version-controlled, peer-reviewed, and reproducible from a clean slate.
GitOps & CI/CD
ArgoCD, Jenkins, and GitHub Actions-driven pipelines that make every deployment automated, auditable, and reversible.
Observability by Default
Prometheus, Grafana, and Loki wired in from day one, so teams can see what's happening before it becomes an incident.
Security-First Automation
Policy, secrets, and access management treated as code - not an afterthought bolted on before an audit.
Built for Reliability & Scale
Resilient, self-service platforms that grow with the business instead of becoming its bottleneck.
