What I Do

Core Competencies

The intersection of architecture, engineering craft, and leadership that I bring to every engagement.

Cloud-Native Azure Architecture

I architect cloud-native platforms that handle enterprise-scale workloads with high availability, security, and cost efficiency. My approach starts from well-architected frameworks and landing zones, then layers in the right services for each workload.

Key Areas

  • Azure Landing Zones & Hub-Spoke network topologies
  • AKS / Kubernetes orchestration for containerised workloads
  • Microservices with Azure Container Apps, Functions & Service Bus
  • Infrastructure-as-Code with Bicep & Terraform
  • CI/CD pipelines in Azure DevOps & GitHub Actions
  • Cost governance, FinOps, and resource tagging strategies

Agentic AI & Copilot Innovation

I integrate AI into enterprise products as a first-class capability — not a bolt-on demo. From building custom Copilot agents with MCP to production RAG pipelines, I focus on AI that solves real business problems at scale.

Key Areas

  • Model Context Protocol (MCP) for agentic tool-use patterns
  • Azure OpenAI Service — GPT-4o, embeddings, fine-tuning
  • RAG pipelines with Azure AI Search & vector indexes
  • Microsoft 365 Copilot extensibility & plugins
  • Prompt engineering & evaluation frameworks
  • Responsible AI guardrails & content safety

End-to-End SaaS Product Development

I build SaaS products end-to-end: from initial product discovery through architecture, implementation, and operational excellence. My sweet spot is turning a 0-to-1 idea into a production workload with clear ownership, observability, and a path to scale.

Key Areas

  • .NET / C# backends with clean architecture & DDD
  • React & Astro frontends with modern TypeScript
  • Event-driven systems with Service Bus, Event Grid & webhooks
  • Microsoft Graph API integrations for Teams, SharePoint & M365
  • Multi-tenant architecture & data isolation patterns
  • Observability with Application Insights, KQL & dashboards

Inclusive Technical Leadership

Technology is a team sport. I lead engineering organisations with a focus on clarity, autonomy, and continuous improvement. I believe the best architectures emerge from teams that feel safe to experiment, challenge, and learn together.

Key Areas

  • Scaling engineering teams from 3 to 20+ across time zones
  • Technical strategy & roadmap ownership
  • Architecture Decision Records (ADRs) & design governance
  • Agile / Scrum coaching & DevOps culture adoption
  • Hiring, mentoring, and growing senior engineers
  • PRINCE2 & ITIL foundations for structured delivery
