Technical Reference Projects

The projects below are designed to demonstrate complete software delivery lifecycles: from domain modelling and C4 architecture to automated Bicep deployments, CI/CD, and live production endpoints.

1. Distributed Systems Reference Platform

A production-style Azure SaaS application designed and implemented using an AI-assisted software engineering workflow.

• Key Concepts: Containerised services, API Gateway/BFF patterns, resilient message handling, and distributed tracing.
• Observability: Centralised telemetry correlation across Service Bus boundaries using Application Insights and Log Analytics.
• Architecture as Code: Visualised using Structurizr DSL and C4 Model container diagrams.

2. Event Sourcing Reference Platform

Demonstrates an enterprise-scale, event-sourced system modeled around mining blast-planning workflows. It replaces traditional CRUD updates with immutable domain events, supporting auditability, historical state reconstruction, and independently scalable read models.

• Architecture: Command Query Responsibility Segregation (CQRS), Domain-Driven Design (DDD), Event Sourcing
• Write Pipeline: ASP.NET Core API validates commands and appends events into Azure Cosmos DB (/streamId partition) with optimistic concurrency.
• Read Pipeline: Committed events are published to Azure Service Bus Topics, where Azure Functions project denormalised views into Azure SQL Database.
• Delivery & IaC: Bicep templates deployed via Azure DevOps multi-stage pipelines with What-If validation.

3. Ticketing Reference Application

Demonstrates pragmatic, production-ready full-stack software delivery without unnecessary architectural overhead.

• Key Capabilities: Dynamic filtering, sorting, pagination, and optimistic concurrency handling.
• Database Design: Isolated within the ticketing schema of a shared database with independent EF Core migration histories.
• Testing: HTTP boundary integration testing using WebApplicationFactory and in-memory SQLite.
