Work

Early-stage SaaS startup with no product, no engineering team, and no technical leadership. Needed someone to own the entire technical build through to pre-seed.

Sole technical leader. Defined the architecture from scratch — .NET 9 monorepo with DDD, serverless Lambdas on AWS, MongoDB, React/Next.js. Designed for scale from the start — thousands of organisations and millions of end users, without overengineering for day one. Designed and integrated AI into the core product — intelligent assistant, workflow automation, and context-aware suggestions. Built the MVP end-to-end — domain logic, auth, data model, frontend, deployment infrastructure. Established engineering practices: CI/CD, Terraform, feature flags, OpenTelemetry. Worked directly with the founder on product strategy and investor-facing technical narrative.

Zero to working MVP. Company secured pre-seed funding. Architecture designed for long-term scalability without premature complexity.

A 20-person software services division bleeding money. A .NET upgrade project was nine months behind, over budget, and dragging billable developers off other work. Division profitability: -630%.

Diagnosed the bottlenecks - the microservices feedback loop was killing velocity. Built internal tooling for instant cross-service feedback, resolved Entity Framework Core migration issues, implemented Scrum, optimised AWS infrastructure, and built a testing roadmap. Also acted as technical sales engineer on proposals from $10k - $500k.

Division profitability: -630% → +36% in six months. Stalled project back to billable work within three months. Promoted to Head of Software Services.

A state government needed a debt management platform serving millions of citizens, including migration from legacy identity systems.

Sole delivery lead. Designed the full system — architecture, Azure B2C auth with custom MFA and just-in-time user migration, built for reuse across future government projects. Worked directly with the department head and UX designers. Delivered ~70% before bringing in additional engineers.

Production platform serving millions of citizens. Auth system handled legacy migration without downtime. Architecture reused on subsequent projects.

Dexus needed to decommission a legacy registry platform and migrate hundreds of thousands of records to a third-party system - governed by GS007 financial assurance standards. No CI/CD, no automated testing, risky manual database fixes.

Primary developer and technical lead on the full migration. Introduced CI/CD and automated testing where there was none. Migrated 3 legacy VB.NET/C++ services to .NET Core microservices. Automated risky manual database operations. Built document extraction with encryption, an Azure APIM gateway, and PowerApps for Dynamics 365 sync. Handled all GS007 compliance.

Hundreds of thousands of records migrated for one of Australia's largest property companies. Legacy services modernised. Manual risk eliminated. Full compliance maintained.

Kalibrate needed to move from a monolith to microservices in Azure. A multi-billion-pound client required bespoke SSO supporting multiple identity providers.

Technical lead. Designed and built an identity broker supporting SAML and OIDC for Azure AD and other providers. Led the migration to a multi-tenant PaaS with event-driven architecture (Azure Service Bus). Introduced Terraform for IaC. Mentored junior developers.

Monolith successfully migrated to microservices. Enterprise SSO delivered. Infrastructure codified with Terraform.

An agriculture SaaS platform had critical data integrity issues - DynamoDB records inconsistent with external systems, cross-application conflicts causing data loss.

Investigated and reconciled DynamoDB inconsistencies using Python. Implemented optimistic locking, GraphQL mutation fixes, and UX workflow changes to prevent overwrites. Reviewed the full stack (React Native, AWS microservices) and proposed observability improvements.

Data integrity restored. Systemic causes fixed. Platform significantly more resilient.
