Senior Site Reliability Engineer · Building Reactas · Tasmania, Australia

I make complex systems trustworthy enough to scale.

Hands-on technical leadership across cloud infrastructure, production reliability, security, and assurance. Through Reactas, I'm applying the same systems practice to rural property resilience.

Selected systems work

Two examples of changing foundations without disrupting the systems that depended on them.

Replatforming without downtime

Constraint: An inherited cloud native product had been designed for speed of development. As the product grew, it became expensive to run and hard to evolve.
Trade-off: The old and new systems had to coexist until every path was proven.
Decision: I redesigned the platform around managed containers and data services, then migrated traffic route by route using staged routing, load balancing, and blue/green deployment patterns.
Outcome: Monthly cloud spend fell by more than 60%, with no migration downtime. Reusable infrastructure patterns made later services faster and safer to stand up. Development velocity was improved through modern CI/CD practices.

Trust designed around real workflows

Constraint: Enterprise sales needed formal security assurance, and customers needed to know that their data is safe.
Trade-off: A conventional compliance programme could easily have overwhelmed a small software company or slowed product work.
Decision: I first modelled how work actually moved through the organisation, then mapped controls onto those workflows, automated evidence, and introduced new process only where the risk required it.
Outcome: The resulting control environment achieved an unqualified SOC 2 Type II opinion followed by ISO/IEC 27001 certification, while product delivery kept moving. Formal assurance stopped being a recurring blocker to enterprise sales.

Discuss technical leadership

Edges are opportunities and failure points.

My work begins with how a system actually behaves: the dependencies, constraints, and feedback that diagrams miss. I look for the smallest structural change that improves the whole, whether the system is digital, organisational, or living.

That often means crossing a barrier instead of optimising one silo: infrastructure and application code, controls and daily work, and maps and direct observation.

Systems engineering has to be holistic.

Reactas

Whole-property planning, with the whole system in view.

Reactas is a geospatial planning environment for improving rural property resilience. It brings public spatial and climate data together with site observations and design reasoning, supporting analysis across fire, water, terrain, and production.

Working tooling. Product in development. The system includes an interactive mapping studio and PDF, GeoJSON, and CSV outputs. Public demonstration through desktop analysis of real estate listings.

About

I'm a senior site reliability engineer and systems builder based in Tasmania, Australia. Over more than 20 years, I've moved between infrastructure, software, reliability, security, assurance, and operations whenever the problem crossed those barriers.

The wider resilience practice grew from the same instinct: observe the whole system, understand the real constraint, and improve it without breaking what already works. I completed a Permaculture Design Certificate and have spent four years applying whole-property design on rural land.
