This series of test-driven small coding puzzles lets you code a database from scratch (no dependencies).We'll cover KV storage engines, LSM-Tree indexes, SQL, concurrent transactions, ACID, etc.

Book 3/3 of the Java Developers Roadmap series, this Senior Level volume dives into the advanced topics you’ll meet in real Java codebases: performance, security, code analysis, utility libraries—and modern frontiers like AI, reactive programming, and Web3. Use it as a roadmap (not a checklist) to level up your technical toolbox with clear explanations, practical examples, and common pitfalls to avoid.

Master the Unity Engine without the fluff of beginner tutorials. Designed specifically for professional developers, this book translates game development primitives into software engineering mental models you already understand. Start building games with the architectural rigor and testing standards you are used to.

JSON succeeded not because it was better--XML had schemas, namespaces, and 10 years of tooling, but because it understood modularity in ways XML never could. This book deconstructs how a deliberately incomplete format defeated a comprehensive standard, then shows you the production patterns (JSON Schema, JSONB, MessagePack, versioning strategies) that make JSON systems scale from prototype to billions of requests.

Change does not fail because of resistance. It fails because people lose clarity and ownership. Spiral Up gives you a simple framework to restore purpose, learning, and momentum at every level.

You already know how to work hard. The question is whether you know when to stop.Most frameworks optimize effort. The Ishi Spiral governs it. It is a discipline of self-governance that sustains performance under pressure without drifting into burnout or grinding past the point where continuation is still justified. The Guide is the Companion to 'Ishi: the Discipline of Determined Intent'.
