Infrastructure as code — declarative, version-controlled provisioning for virtualization and cloud.

Read-only, multi-vendor network config backup over SSH/telnet/API — Cisco IOS, MikroTik RouterOS, OPNsense, Ubiquiti EdgeOS/EdgeSwitch, Lantronix, Digi, and Proxmox SDN. Inventory-driven, secrets-free.

Application projects — Python tooling, CLIs, and integrations that support network and infrastructure operations.

Cisco ACI — data-center spine-leaf fabric design, policy, and APIC automation.

Multi-cloud automation across AWS, Azure, GCP, and Oracle Cloud — provisioning, hybrid connectivity, and cost-controlled operations.

Cisco ISE & Zero-Trust network access control — policy design, 802.1X/MAB, and a reproducible automated ISE 3.4 lab.

Build a self-contained Cisco ISE 3.4 + Windows Server 2025 AD lab on Proxmox with Ansible — one role provisions both VMs; unattended DC (forest+DNS+authoritative NTP), serial-driven ISE setup, gotchas documented.

Web projects — Astro / static sites behind a hardened self-hosted WAF edge with CI/CD.

Ansible — idempotent provisioning and configuration management for network and compute.

Self-service multi-vendor security demo lab (Cisco ISE + WLC + Palo Alto) on Proxmox — a gated portal to rebuild/reset and drive API automation, reset from golden snapshots.
