02 — Trade-off Analysis Frameworks

Patterns

A book-shaped table of contents for reusable engineering patterns spanning object-oriented design, enterprise architecture, distributed systems, messaging, APIs, cloud infrastructure, observability, security, concurrency, AI/agentic systems, and organizational design — grounded in production experience at scale.

01 — Decision-Making Patterns

Buy vs. Build, Build vs. Platform, Sync vs. Async, SQL vs. NoSQL, and Monolith vs. Microservices — recurring architecture forks and the questions that actually resolve them.

02 — Pattern Selection & Trade-offs

How to choose between competing patterns under real forces: naming the context, weighing trade-offs and consequences, composing multiple patterns together, and recognizing when a pattern has outlived its fit.

03 — Transaction Patterns

Unit of Work, Identity Map, Lazy Loading, and Optimistic vs. Pessimistic Locking — the patterns that keep an object graph and its persisted state from drifting apart.
