Mark Robillard Jr — Hybrid Cloud Platform Engineering

Platform engineer focused on Linux-first infrastructure, private cloud (Proxmox/KVM), and hybrid cloud integrations (AWS/GCP) that stay observable, cost-aware, and maintainable.

$ focus: hybrid cloud networking • secure access • automation • reliability • pragmatic architecture

Linux / Debian / RHEL Proxmox • KVM/QEMU VPN • routing • VLANs IAM • MFA • PAM Containers • CI/CD Self-hosted control planes

What I Build

Hybrid Cloud Connectivity

Private cloud + public cloud linked with sane network boundaries and clear operational ownership.

Site-to-site and client VPN patterns
Routing, segmentation, and access controls
"Works at 2AM" troubleshooting workflows

Private Cloud Platforms

Debian/Proxmox-based virtualization stacks with automation and guardrails.

VM provisioning (cloud-init)
Standardized templates + lifecycle hygiene
Cost control via simplicity

Security & Auth Systems

Authentication flows that are usable for humans and defensible for ops/security.

PAM integrations, MFA (OATH/OTP patterns)
Credential workflows and least privilege
Pragmatic hardening on Linux

Automation & Tooling

Small tools that remove toil and keep infrastructure understandable.

Bash/Python automation + packaging
.deb build pipelines and release hygiene
Monitoring and operational dashboards

Technical Focus

Platforms

Debian/Ubuntu, RHEL
Proxmox, KVM/QEMU
Containers + service orchestration patterns

Networking

VPNs, VLANs, bridges, routing
Network boundaries + access models
Operational debugging (packet-level when needed)

Security

IAM concepts, MFA patterns
PAM, secure auth flows
Hygiene: patching, keys, least privilege

Languages

Python, Bash, Java
C++ (systems tooling), JS (when needed)
PHP (pragmatic web endpoints)

Hybrid Cloud Playbook

What I care about: predictable deployment paths, clean rollback, clear network ownership, and security that doesn't break usability.

mentalnet@ops:~$ ./hybrid_cloud_checklist.sh

[✓] Private cloud baseline (templates, patching, backups)
[✓] Connectivity model (site-to-site / client VPN / zero-trust where appropriate)
[✓] Network segmentation (VLANs / security groups / routing rules)
[✓] Identity + access (MFA, least privilege, audit trail)
[✓] Observability (logs, metrics, alerts with actionable signal)
[✓] Automation (repeatable provisioning + config)
[✓] Cost sanity (no "cloud tax" without a reason)

Tools
