Shipping AI Features Under HIPAA
Adding an LLM to a product that touches protected health information changes who your subprocessors are, what your logs contain, and what you must be able to prove. An engineering view of the constraints.

What Is AI Readiness?
AI readiness is whether an organisation can actually put AI into production and keep it there. It is mostly a data, governance and operations question, and almost never a model question.

EU AI Act, August 2026: What Applies to Software Teams
The Act's most consequential obligations landed on 2 August 2026, and some were then moved. What is in force now, what shifted, and what an engineering team building AI features should actually do about it.
Engineering
What Are Story Points? Origin, Fibonacci Scale, Velocity and Criticism
Story points are a unitless, relative measure of how big a piece of work is compared with other work, used with a team's velocity to forecast delivery.

AI Build vs Buy: A Decision Framework
Most AI build-versus-buy decisions are made on cost and regretted on control, or made on control and regretted on maintenance. A framework based on what is actually differentiating for your business.

What Is a Schema Migration?
A schema migration is a versioned, ordered script that changes a database's structure. Here is how up/down, expand/contract and zero-downtime changes work.

How to Estimate the Cost of an AI Feature
AI features have a cost structure traditional software does not: it scales with usage, varies per request, and is set by design decisions made months earlier. A method for estimating before you build.
Engineering
What Is a Rate Card?
A rate card lists what each role costs per unit of time. It looks like a pricing artefact and functions as a planning one - it is how a scope estimate becomes a number someone can approve.

Small Language Models vs Frontier Models: A Cost Framework
Serving a 7B model is roughly 10-30x cheaper than a frontier model for tasks where accuracy is equivalent. The engineering question is which tasks those are, and how to find out without guessing.
Engineering
What Is a PRD (Product Requirements Document)?
A PRD states what should be built and why, precisely enough that engineers can build it without guessing. In a world where implementation is cheap, the specification became the constraint.

What Is an AI Memory Layer?
Chat history is not memory. A memory layer is durable, retrievable state about decisions, preferences and facts that survives past the context window. What belongs in one, and what should stay in a log.
Engineering
What Is a Code Smell?
A code smell is a surface indication that usually corresponds to a deeper problem. The word 'usually' is the whole point, and it is the part that gets dropped when smells become lint rules.
