Engineering notes on AI, ML, custom apps, and the messy bits of shipping production software.
AI agents are real, useful, and easy to oversell. Here is a plain English look at what they do well today, where they still need a human, and how to start.
A practical, ordered playbook for lowering production LLM costs. Prompt hygiene, caching, model routing, retrieval, budgets, and the measurement that ties it all together.
A practical guide to building an AI assistant grounded in your own handbook, policies, and support history, plus the failure modes to avoid.
A practical AI development guide. When retrieval works better than fine tuning. When prompt engineering wins. And the cost equation most teams skip.
