Not sure if this is the right fit?
Consider Agile Software Development, Principles, Patterns, and Practices by Robert C. Martin.
“Practical, code-first manual aimed at hands-on developers; it mixes object-oriented design, UML, design patterns, and Agile/XP practices with long C and Java examples. The most useful parts are concrete problem-solving walk-throughs: refactorings, design choices, and pattern implementations you can copy into real projects. Limitations: heavy on language-specific listings and prescriptive editorializing — the tone can feel didactic, and some examples read dated compared with modern language features. Not a gentle introduction; it's best used slowly and with a code editor open.”
