Projects

Tools built around the Citrix, VMware, and Windows work I do day to day. Each one has a page you can try in the browser with synthetic data, automated tests, and documentation of what still has to be validated in a real environment.

Citrix Catalog Baseline

v0.1.0

Access review for Citrix machine catalogs: every user who can start a desktop and the exact group and rule path behind it, the installed software, and deterministic recommendations such as disabled accounts with access or drifted persistent machines.

Review page: browse catalogs, compare their users and software, look up a user, and export any table to CSV.

Citrix Exporter

v0.2.0

Prometheus exporter for Citrix Virtual Apps and Desktops: VDA registration, sessions, logon duration, licenses, and MCS catalogs, with alert rules and a provisioned Grafana dashboard.

Metrics Playground: change a synthetic site and watch /metrics, the alert rules, and a panel react.

PowerShell 7PrometheusGrafanaDocker

DR Orchestrator

v0.2.1

Dependency-aware disaster recovery runbooks in YAML: validation before execution, ordered recovery across VMware and Windows, failure propagation, and Markdown/HTML reports.

Runbook Viewer: read a recovery runbook as a procedure, mark steps to fail, and run a simulated drill.
