About

Technology leadership from strategy to production.

I help organisations turn complex technology challenges into practical platforms, products and roadmaps. My work spans concept development, architecture, delivery leadership, application modernisation and building high-performing engineering teams.

01

Cloud platforms

Azure architecture, SaaS/PaaS platforms, modernisation and reliable cloud operations.

02

Product leadership

Product strategy, discovery, market fit, prototyping and paths from MVP to scale.

03

Technology advisory

Clear roadmaps and investment decisions grounded in commercial outcomes and delivery reality.

04

AI & automation

Designing agent-based systems that combine AI reasoning, cloud telemetry, automation and human approval. Current work includes agent orchestration, durable background workflows, infrastructure operations, model integration and governed access to cloud environments.

Current focus

What I’m building now.

My current work focuses on making cloud platforms increasingly self-managing. This brings together Azure architecture, platform engineering, observability, automation and AI agents that can identify operational issues, recommend actions and safely carry out approved changes.

01

AI-agent architecture

Designing specialised agents for cloud operations, deployment, diagnostics, optimisation and customer support.

02

Agent orchestration

Building asynchronous workflows using containerised workers, queues, managed messaging, retries and durable task execution.

03

Cloud intelligence

Bringing together platform telemetry, logs, cost information and operational context so agents can make evidence-based decisions.

04

Human-guided automation

Creating approval boundaries, access controls, audit trails and safeguards for agent-initiated infrastructure changes.

Selected experience

A career built around products, platforms and people.

Trusted advisor

Created long-term client partnerships.

Helped Simply Energy deliver Australian-market firsts and meaningful customer-experience improvements.

Founder & business builder

Built folio1 into a successful technology consultancy.

Grew the organisation to 12 staff and 20 contractors, establishing strategic partnerships, sales capability and end-to-end delivery.

Product leadership

Developed more than 50 products.

Led products from discovery and market fit through prototyping, MVP, commercialisation and scale.

People leadership

Built high-performing, distributed technology teams.

More than 10 years leading teams with up to 12 direct and 20 functional reports, with a focus on recruitment, development and retention.

Strategic partnerships

Became the region’s leading Progress Software solutions partner.

Established relationships with Microsoft, AWS, Atlassian, Sitefinity, SnapLogic, DocuSign and other technology leaders.

Service delivery

Built services supporting more than 1 million users.

Delivered solutions across 750 clients and established a 24/7 support capability underpinned by SLAs and IT service-management processes.

Also worked with Timelio, Raw Materials, Global Supply Line and RCI.

Current venture

KloudStack

Building an AI-native operational control plane for cloud infrastructure.

KloudStack is being developed to help organisations deploy, operate and optimise cloud platforms through intelligent agents guided by human insight. The goal is to move beyond traditional dashboards and manual cloud management toward platforms that can understand their own operational state, identify problems and coordinate safe corrective actions.

The platform brings together cloud automation, observability, infrastructure context and AI reasoning. Agents are being designed to assist with deployment, health monitoring, incident investigation, performance optimisation, security review and cost management.

Agent platform development

Exploring agent runtimes built around Azure Container Apps, containerised workers, durable messaging and managed state. The architecture supports scheduled and event-driven work, retries, dead-letter handling and long-running operational tasks.

Azure platform engineering

Designing and operating production Azure environments using App Service, Azure Container Apps, Front Door, WAF, private networking, managed databases, storage, Redis, Service Bus, Application Insights and Log Analytics.

Operational intelligence

Developing ways for agents to reason over telemetry, deployment state, application health, security events and cloud costs—while keeping consequential infrastructure actions visible, governed and auditable.

Current platform work

  • Operating managed Azure application stacks
  • Developing container-based agent workloads
  • Designing durable task and messaging architectures
  • Building cloud monitoring and diagnostic automation
  • Exploring Azure AI Foundry and multiple-model integration
  • Developing AI-assisted cloud operations and governance
  • Operating production WordPress PaaS infrastructure
  • Creating reusable deployment and operational patterns
