I Architect Cloud Systems On AWS_

Healthdirect Australia is the national public health service funded by the Commonwealth and state governments — an environment where availability, clinical safety, auditability, and WCAG accessibility are compliance obligations rather than goals.

• Engineering lead on national health platforms for over four years, taking products from greenfield to public launch and then operating them through a sustained weekly release cadence
• Architected ORE Management Studio, an enterprise clinical-rules management platform in Next.js and TypeScript, giving clinical staff direct control over triage logic that previously required an engineering change to alter
• Designed the identity and authorisation model on AWS Cognito using OIDC with role-based access control, including secure token handling and separated credential management across development, staging, and production
• Built Symptom Checker, a public clinical triage application, with server-side rendering for first-load performance and accessibility treated as a launch gate rather than a follow-up
• Delivered high-volume clinical data views with AG Grid and automated multi-sheet Excel reporting, replacing a manual operations process
• Also delivered the account management system for the healthdirect mobile app and the Service Finder product, working across Next.js, Angular, Ionic, and Cordova codebases

Impact: Both launch platforms went live on the committed May 2022 date and remain in national service, shipping incrementally every week since.

Stack: Next.js, TypeScript, AWS Cognito, React, Chakra UI, AG Grid, Angular, Ionic

• Delivered a public-facing web application for the Victorian Government's Suburban Rail Loop East infrastructure programme, brought in on a fixed end-of-year deadline and delivered on it
• Built the React frontend and Node.js services, deployed on Azure — a short, scoped engagement where the constraint was time-to-live rather than long-term platform work

Stack: React, Node.js, Azure

• Led the re-architecture of a Buy Now Pay Later platform from a monolith onto a fully serverless AWS stack, chosen to remove idle infrastructure cost and let the platform absorb spiky transaction volume without capacity planning
• Designed and built the core REST API in NestJS and TypeScript, deployed to AWS Lambda behind Amazon API Gateway using the Serverless Framework, with environments defined as code and promoted rather than hand-configured
• Implemented the authentication and authorisation layer — email-based auth via Passport.js with role guards enforcing least-privilege access to financial endpoints
• Chose NestJS specifically for its module and dependency-injection model, so a small team could add payment flows without the service becoming a shared mutable surface
• Published an OpenAPI/Swagger contract as the integration boundary, unblocking frontend and third-party work in parallel with backend delivery

Stack: AWS Lambda, API Gateway, Serverless Framework, NestJS, Node.js, TypeScript, OpenAPI, Passport.js

Perpetual is an ASX-listed investment and trustee group managing funds for individuals, advisers, and institutions — an environment where financial accuracy and auditability are non-negotiable.

• Engineered the corporate trust management platform within Perpetual Business Intelligence, then extended the same codebase to carry the payments and registry products rather than forking a second application
• Built financial ledgers, reconciliation tables, and charting over large datasets with AG Grid, and embedded Power BI for real-time reporting instead of rebuilding analytics in-house
• Generated a strongly typed TypeScript client from the OpenAPI 3.0 contract using NSwag, eliminating a recurring class of frontend/backend drift bugs on a regulated data model
• Worked across the stack into .NET Core services and RESTful API design, and used RxJS extensively for the platform's asynchronous data flows
• Deployed and operated on Azure across the delivery pipeline

Impact: Delivered ahead of deadline through a fully remote period, and consolidated three products onto one maintained codebase.

Stack: Angular, TypeScript, RxJS, AG Grid, Power BI, .NET Core, OpenAPI/NSwag, Azure

• Lead engineer on My Community Project, a greenfield state-wide participatory budgeting platform — 61,437 NSW citizens cast votes, directing A$24.7 million of public funding to winning community projects
• Architected it full stack: React and Next.js with server-side rendering for public reach and SEO, and a Node.js, Prisma, and GraphQL backend with Apollo Client, chosen over REST to keep a rapidly changing data model from forcing endpoint churn
• Built the NSW Police Force firearms licence application, which has processed several thousand applications per month since launch without a production outage
• Delivered an eligibility-assessment platform for NDIS support workers, handling sensitive personal data under government privacy obligations
• Introduced Docker containerisation to make scaling and environment parity predictable across the delivery pipeline

Impact: Both citizen-facing platforms launched and remain in service; the voting platform is the highest-scale public system I have led the frontend architecture for.

Stack: React, Next.js, GraphQL, Apollo, Node.js, Prisma, Angular, TypeScript, RxJS, Docker

• Joined a home-loan origination platform, State Custodians, that was already behind schedule, and got version one live on the original date
• Implemented the financial calculation layer — repayments, stamp duty, loan comparison, and eligibility rules — where an error is a compliance issue, not a bug
• Structured application state with NgRx to make those calculations traceable and testable rather than scattered across components
• Applied route-level lazy loading to cut subsequent page load times on a large Angular application
• Worked in the Azure DevOps and ASP.NET toolchain across delivery and deployment

Stack: Angular, TypeScript, NgRx, ASP.NET, Azure DevOps

• Built "Floods Near Me" for NSW Public Works Advisory — a public emergency-information mobile app where responsiveness under load matters most during the event it exists for
• Moved heavy geospatial data processing off the main thread into web workers, holding a sustained 60fps interface on mid-range devices
• Shipped one Cordova codebase to both iOS and Android, styled with Angular Material and Flex Layout to read as native on each platform
• Deployed and monitored on Azure; also delivered an Angular mobile application for Telstra

Stack: Angular, Ionic, Cordova, Web Workers, SASS, Azure
