.NET architecture built for the decade after this one, not just this release.

A migration from .NET Framework to .NET 8 or 9 that just recompiles the existing codebase against the new runtime captures a fraction of the available value. We architect around Clean Architecture and domain-driven boundaries from the outset — application logic organized around business capability, with minimal APIs replacing the controller-heavy MVC patterns that accumulated cross-cutting concerns over a decade of feature work.

Dependency injection, configuration, and cross-cutting concerns (logging, validation, authorization) are standardized through a shared internal framework layer we build once per engagement, so every new service starts from the same disciplined baseline instead of reinventing infrastructure code project by project.

Microservice decomposition follows Conway's Law deliberately: service boundaries are drawn to match the team structure that will own them long-term, not an idealized domain model that no single team is actually staffed to maintain. Each service is containerized with a minimal, distroless base image, built through a standardized CI pipeline, and deployed to Azure Kubernetes Service with resource limits and health probes configured from day one — not added retroactively after the first out-of-memory incident.

Cross-service communication defaults to asynchronous messaging via Azure Service Bus for anything that doesn't require a synchronous response, with saga-pattern orchestration handling distributed transactions that span service boundaries. Synchronous service-to-service calls, where unavoidable, go through a service mesh layer for consistent retry, circuit-breaking, and mutual TLS — so resilience isn't hand-rolled differently in every service.
