Go beyond simply asking AI to write your code. This four-book bundle shows you how to use Claude Code across the software lifecycle, from building full-stack applications and understanding existing codebases to static analysis and MCP-powered workflows. Whether you are learning the basics or looking to improve the way you already work, these practical guides give you the knowledge, techniques and hands-on examples to put Claude Code to work on real engineering problems.

AI can write code. Testing can find bugs. Formal verification can prove properties. But how do you bring all three together without making software development unnecessarily complicated? This three-book bundle takes you from AI-assisted verification with Claude Code through practical testing and software quality to the foundations of formal verification, giving you a clear path toward building software you can actually trust.

The complete LLM Engineering collection—from a single weight to production systems that fail silently. Explore how LLMs work, how to build and optimise them, and how to diagnose the failures that matter.

Two forensic collections. 110 real investigations into C++ and LLM systems that compile, run, and quietly lie. Trace the evidence, uncover the root cause, and see how each failure was fixed.

Four handbooks for people who run Claude Code every day: what it costs and how to cut that, what to do when a release changes the rules under you, the guards worth installing before anything else, and how to keep one instruction file working across nine tools. Over 460 pages, written from an operator's own logs and incidents rather than from the documentation. Every book has a free sample, and updates are free to buyers.

Claude Code is changing the way developers build and understand software, but getting real value from it takes more than asking it to write code. This three-book bundle shows you how to use Claude Code from the ground up, build production-ready full-stack applications and work with existing software systems through practical reverse engineering workflows. With hands-on projects, real-world techniques and a strong focus on good engineering practices, this collection gives you the skills to use Claude Code confidently across the full software development lifecycle.

Almost everything written about large language models is advice. This series measures it. Nine volumes, 609 pages, built and run on a single CPU core with no access to a large model —and that constraint produced the method rather than limiting it. Several results contradictedthe advice they were testing: hybrid retrieval lost in every condition, neither reranker beatthe noise floor, and unstructured pruning saved not one byte. One experiment turned out to be confounded. It is in the book alongside its correction, becausethe mistake was more instructive than the finding.

Ready to go beyond basic AI coding? This three-book bundle takes you from mastering Claude Code to building production-ready full-stack applications and creating your own AI agents with the Claude Agent SDK. Packed with practical examples, hands-on projects and real development workflows, it gives you a clear path from your first AI-assisted coding session to deploying serious applications and agent systems in production.
