Harness Engineering: How AI Development Earns Its Place in Regulated Software
The agent generates; the harness decides what counts. In regulated domains, harness engineering is the discipline that turns a stochastic coder into an auditable one.

Two Lines of Defence Against Drift in SDD-Built Distributed Systems
Golden tests and runtime conformance probes guard different lifecycle stages — together they make spec drift visible before and after merge.
Demistifying Event Sourcing (2 of 5): same name, very different beasts
Event sourcing and event-driven architecture share a word and almost nothing else. One is a persistence strategy, the other a communication style, and conflating them leads to bad designs.
Spec-Driven Development: Drift, Trade-offs, and the Roles That Must Adapt
When the spec is the source and the agent is the compiler, drift becomes the new bug class — and every classical role has to retool around it.

The EIP Process Manager Pattern with Temporal, Spring Boot, and Hexagonal Architecture
The Process Manager pattern gives long-running business workflows an explicit, stateful home — and Temporal is the infrastructure that makes that state durable without leaking into your domain.
Demistifying Event Sourcing (1 of 5)
A part-by-part deep dive into event sourcing through five myth-busting articles.
Event-Driven Architecture: When and Why
A practical look at when event-driven patterns solve real problems, and when they add unnecessary complexity.
Database-per-Service: The Microservices Data Boundary
Why each microservice should own its data store, and the real costs of enforcing that boundary.
Caching Strategies: Cache-Aside, Write-Through, and When to Use Each
A systematic breakdown of caching patterns, their consistency guarantees, and the failure modes you need to plan for.
Tracking Software Architecture Decisions
How to maintain a traceable record of architecture decisions that satisfies compliance requirements without drowning your team in documentation.
