About

Master's student in Business Systems Organization with a background in Information and Business Systems. I work on cloud-native platforms, infrastructure automation, delivery workflows, and observability, with a focus on making systems reliable, understandable, and repeatable.

My interests are platform engineering, infrastructure as code, GitOps, monitoring, and developer tooling. I also bring experience from software, data-driven, and interactive-development projects, plus international teamwork through an Erasmus+ exchange at the Faculty of Engineering, University of Porto.

💡 Most of my day-to-day engineering work is maintained on a private GitLab instance at SICK Mobilisis and through faculty projects, so those contributions are not reflected in the GitHub activity graph.

Tech Stack

Area Technologies and practices
Platform and delivery Kubernetes, Docker, GitOps, Argo CD, CI/CD
Infrastructure as code Terraform, YAML, declarative configuration
Observability Prometheus, Grafana, Loki, alerting
Cloud and identity Azure, OAuth 2.0, OpenID Connect
Development TypeScript, Python, C#, JavaScript, .NET

Current Direction

  • Public examples of infrastructure automation, GitOps workflows, observability, and developer tooling.
  • Small MCP tools that make durable knowledge and operational context easier to use.
  • Projects that connect software delivery with clear documentation and repeatable validation.

Education

  • Master's degree in Business Systems Organization, Faculty of Organization and Informatics, University of Zagreb
  • Bachelor in Information and Business Systems, Faculty of Organization and Informatics, University of Zagreb
  • Erasmus+ exchange at the Faculty of Engineering, University of Porto
