DevOps, Automation & Development
Personal brand built by Sebastian Grbovic, a junior DevOps engineer focused on automation, scalable systems and practical engineering.
"Maskin Developments represents a focus on structured, reliable and efficient systems. Built on hands-on experience in DevOps, scripting and modern infrastructure."
CI/CD pipelines, GitOps workflows, automated deployments. Building systems that ship reliably from commit to production.
Kubernetes, Linux environments and scalable system design. Infrastructure built to be understood, maintained and extended — not just deployed.
Python scripting, automation tooling and web development. Code written to solve real problems in real environments — not over-engineered.
Middleware service that receives Prometheus Alertmanager webhooks and forwards structured Adaptive Card alerts to Microsoft Teams via Power Automate. Alert data is logged to Elasticsearch indexed by date.
GitOps deployment pipeline for a FastAPI service. GitHub Actions builds and pushes container images to Docker Hub, then automatically updates the dev overlay's image tag for ArgoCD to sync. Production is promoted via a separate Kustomize overlay.
Terraform and shell scripts for bootstrapping a Kubernetes cluster with Prometheus, Grafana and ArgoCD pre-configured. Opinionated observability starter kit.
