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 straight, vendor neutral answer to the question every founder is asking right now. Most teams do not need custom AI yet. Here is how to tell when you do.
A practical guide to building an AI assistant grounded in your own handbook, policies, and support history, plus the failure modes to avoid.
Hype free engineering principles for AI products that serve users, not nudge them. Grounding, refusal, evals, cost bounding, the boring decisions that actually ship.
A practical AI development guide. When retrieval works better than fine tuning. When prompt engineering wins. And the cost equation most teams skip.
What you can realistically ship in a 4 week custom app MVP, features, tradeoffs, and the timeline traps that kill startups.
A working model is not a working product. The full production ML stack, data pipelines, deployment patterns, monitoring, and drift detection.
