About ArchitectMind

ArchitectMind is written by Mahesh, a Senior Technical Architect who has spent his career delivering Java-based enterprise applications. The site grew out of a personal study library: ten books and seventy volumes of notes written to cover the full path from Core Java to solution architecture, in the order an engineer actually needs it.

What you will find here

• A single learning path. Ten books in four stages: foundations (Core Java, the JVM, Jakarta EE), frameworks and design (Spring, design patterns), systems (data, integration, distributed systems, quality attributes) and production and architecture (cloud, DevOps, security, system design and solution architecture).
• The same ten sections on every topic. Concept, why it exists, core concepts, how it works internally, APIs and code, practical examples, common mistakes, production considerations, architecture considerations and interview questions.
• Interview questions at five levels. From Basic to Solution Architect, with full answers, so you can practise the level you are at and the one above it.
• Modern baselines. Java 25, Spring Framework 7 and Spring Boot 4, Jakarta EE 11 and current cloud practice.

How the tutorials are written

Every tutorial explains how a technology works and also why you would choose it, what it costs in production and how to defend that choice in a design review. Worked examples use realistic systems, such as an online retailer, a payments platform, a bank and an insurer, so the trade-offs are concrete. Drafts are reviewed and expanded before publication, and pages are updated when the underlying technology changes.

How the site is published

The library is published in rounds. Each round adds the next topic in every one of the seventy volumes, so the whole path grows evenly rather than one book at a time. The first three rounds are live: 210 tutorials, from Core Java to solution architecture, with more than 1,800 interview questions.
