About me

I turn cloud complexity into a competitive advantage.

I'm a freelance Azure Cloud Architect and DevOps Engineer with 9+ years of experience designing enterprise-grade cloud solutions.

I focus on building secure, scalable and cost-efficient Azure landing zones, CI/CD pipelines and Kubernetes platforms — with observability and compliance baked in from day one. I help teams migrate on-prem applications to modern cloud architectures and remove cloud complexity so they can focus on what really matters.

Outside of work I follow frontend development and emerging tech, and I'm a passive investor.

What I do

End-to-end Azure &
DevOps expertise

From initial architecture design to production automation — I cover the full cloud delivery lifecycle.

Azure Landing Zones & Architecture

Greenfield and brownfield enterprise-grade cloud foundations with governance, identity and networking designed in from day one.

  • Hub-and-spoke / vWAN topologies
  • On-prem application migration
  • Identity & Entra ID design
  • Cost management baseline

CI/CD & DevOps Automation

Reliable, fast and secure pipelines that eliminate manual work and let your team ship with confidence every day.

  • Azure DevOps & GitHub Actions
  • Source code quality & security gates
  • Artifact & container registry management
  • Release management & rollback strategies

Kubernetes & Containers

I design and run production-ready AKS clusters — from network architecture and RBAC to autoscaling and GitOps workflows.

  • AKS cluster design & setup
  • Helm chart authoring
  • GitOps with Flux / ArgoCD
  • Nginx & Cilium

Infrastructure as Code

Maintainable, modular IaC codebases that reduce drift, enable self-service and pass any audit.

  • Modular Terraform & shared workspaces
  • Azure ARM templates
  • Remote state, locking & drift detection
  • Secret management & rotation

Observability & Monitoring

Know about issues before your customers do. I build end-to-end observability — from metrics and logs to distributed tracing.

  • Azure Monitor, App Insights
  • Prometheus
  • SLO / SLA dashboards, alerting
  • Grafana

Security & Compliance

Security by design, not as an afterthought. Zero-trust networking — so audits stop being stressful events.

  • Defender for Cloud
  • Azure Policy, guardrails
  • Key Vault, managed identity
  • ISO 27001 / NIS2 compliance
Results

Real transformations,
measurable results

The numbers speak for themselves. These are projects where good architecture directly moved the business.

FinTech Azure · AKS

Microservices migration for a Czech payment processor

Migrated a monolithic .NET application to containerized microservices on AKS with full CI/CD, autoscaling and PCI-DSS-aligned network segmentation.

Logistics SecDevOps · IaC

Security scanning embedded directly into DevOps pipelines

Rolled out DevSecOps in a logistics company — SAST, DAST, container image scanning and IaC analysis as mandatory gates in Azure DevOps pipelines.

HealthTech Landing Zone

GDPR-aligned Azure landing zone for a healthcare SaaS

Designed a multi-subscription Azure foundation with private endpoints, RBAC governance, Defender for Cloud and automated GDPR data-residency checks.
