Eldwyn “Tank” Mathieu

Systems & Infrastructure Engineer

I build secure, self-hosted platforms with clear trust boundaries, reversible changes, and operational discipline.

Professional Snapshot

Over two decades of experience in information technology, communications, and systems operations
Background spanning military communications, enterprise IT, education networks, and private infrastructure
Focused on live, production systems—not prototypes or demos
Security-conscious, documentation-driven, and operations-first
Comfortable across infrastructure, networking, backend services, and human-facing systems

Core Platforms & Systems

WizardAtWork Platform — A self-hosted, multi-service production domain consolidating infrastructure, services, and community platforms under a single operational umbrella.

Private Cloud & Virtualization — Multi-node Proxmox environment supporting isolated workloads, snapshot-driven rollback, and controlled resource allocation.

Edge & Reverse Proxy Services — Centralized NGINX edge handling TLS termination, domain routing, service isolation, and controlled public exposure.

Secure Communication & Collaboration — Self-hosted messaging and collaboration services designed with strict separation of authority and privacy controls.

Flagship Architecture — WizardAtWork

WizardAtWork is not a single website, but a platform ecosystem integrating web services, private cloud infrastructure, collaboration tools, monitoring, and security controls into a cohesive system.

The platform follows a disciplined operational philosophy—internally referred to as Granite Mode—focused on explicit trust boundaries, minimal surface area, reversible changes, and auditability.

Advanced Systems Architecture

The Many-Faced God

A multi-agent AI architecture built around role separation and neutral memory. Specialized operating environments act as independent “faces” that observe and analyze, while a neutral core canonizes immutable, append-only memory.

Role-separated operating systems with no shared authority
Immutable, auditable memory as the single source of truth
Human-in-the-loop interaction without memory ownership
Zero-trust internal design

Live Systems Platform

Multiplayer Backend & Live Operations

A real-time, multi-user backend platform built on the FiveM/QBCore ecosystem. Architected as a modular, stateful services platform supporting persistence, role-based permissions, and continuous updates without data loss.
