Engineering Journey
From first-line support tomodern platform engineering.
More than two decades of infrastructure operations, technical leadership, continual learning and adaptation to changing technology.
Continuous Development
Experience that evolves with technology.
My career began in technical support and developed through enterprise infrastructure, UNIX, Linux, infrastructure management, governance and technical leadership.
As infrastructure delivery evolved from local server rooms to hosted data centres, cloud services and container platforms, I continued developing my skills and applying existing operational experience to new technologies.
The current stage of that journey brings together Linux, infrastructure operations, cloud platforms, automation, observability, security and structured technical delivery.

Cloud
AWS, Azure, Terraform, remote state, IAM and reusable infrastructure components.
Platforms
Docker Compose, Kubernetes, K3s, ingress, networking and operational platform design.
Observability
Prometheus, Grafana, Loki, exporters, dashboards and alerting.
Security
Cloudflare, Authelia, MFA, CrowdSec, threat detection and automated firewall response.
Engineering Philosophy
Good engineering is more than making something work.
Throughout my career, I have aimed to leave systems more stable, understandable and supportable than I found them.
Supportable
Technology should be understandable and maintainable by the teams responsible for operating it.
Observable
Health, performance and failure conditions should be visible through metrics, logs and alerts.
Secure
Access, external exposure, operational risk and threat response should be considered from the beginning.
Repeatable
Automation, documentation and version control should reduce reliance on individual knowledge.
Business-aware
Engineering decisions should account for service continuity, cost, risk and organisational outcomes.
Continually improving
Platforms and processes should evolve as technology, requirements and operational understanding develop.
