Infrastructure & Systems Engineering

Baden John

I work the layer beneath the application — bare-metal deployments, container sandboxing, hypervisor optimization, and the network routing that keeps it all reachable.

I keep virtualization overhead low, track services natively with systemd, hold tight perimeter access rules, and favour bare-metal where it earns its place.

Projects

Bare-Metal Container & VM Server

A high-reliability local cluster providing low-overhead container orchestration and isolated virtual networks — built for predictable behaviour under load.

High-Tickrate Game Infrastructure

Optimized multi-process execution environments on Linux systemd daemons — managing socket bindings, port mapping, and firewall traversal to hold a stable tickrate end to end.

Experience

IT Assistant Placement

University of South Wales 2024 — 2025

Identity & access management. Maintained enterprise user trees, credential updates, and centralized domain group policies via Active Directory.
Hardware & software triage. Diagnostic isolation on workstation nodes, board-level fault checks, and system image restoration.
Compliance auditing. Tracked and parsed platform event logs to maintain security baselines and catch unauthorized changes.
