Why Open Source
Open source means ownership: you control your data, your configuration, and your future roadmap. No hidden licensing traps and no “black box” systems that only one vendor can fix.
I build Linux-first environments that are documented, automated, and auditable. The goal is simple: fewer surprises in production and less time spent firefighting.
If your IT feels messy—too many tools, unclear responsibilities, missing documentation—I turn it into a clean, maintainable system with clear boundaries and repeatable operations.

Security & Resilience
Hardening and recovery planning that actually gets tested.
- Firewall/VPN segmentation and access control

Proof
Stabilised Operations for a Small Business
A growing environment with undocumented changes, inconsistent server setups, and recurring outages.
- Standardised builds with Git-backed automation
- Introduced monitoring, alerting, and clear ownership
- Reduced incidents and improved recovery confidence
Security and Access Cleanup
Legacy access patterns, weak segmentation, and unclear audit trails across systems and accounts.
- Tightened access control and hardened the perimeter
- Improved credential handling and operational hygiene
- Clear logs, documentation, and repeatable change process
How Engagements Work
We clarify goals, constraints, and what “good” looks like.
You get a short written plan: risks, priorities, and the delivery approach.
Implementation via Git-backed automation with clear change tracking.
Monitoring, documentation, handover—and optional ongoing support.
