The "It Works on My Machine" Excuse Ends Today. Understand Docker. Ship with Confidence. Own Production. This book is written for front-end developers who are tired of using Docker without truly understanding it. Instead of abstract theory or backend-centric explanations, it teaches Docker in a clear, practical way—aligned with how front-end engineers think and how real front-end applications are built and shipped.You’ll work with a real GitHub repository, follow real production workflows, and learn how to build, run, and deploy a React.js application using Docker—ending with a full deployment to Amazon EC2. Every step is explained with purpose, so you understand not just what to do, but why it works.By the end of the book, Docker will no longer feel like a black box. You’ll know how to create reliable builds, debug problems with confidence, and take ownership of your production environment as a front-end developer.If you want to stop guessing, stop copying commands, and finally ship front-end applications with confidence—this book is for you.

Building a chat feature over your product docs? You need a vector database.Adding recommendations to your app? Vector database.Searching 100 million images by visual similarity? Definitely a vector database.Yet most engineers stumble into these projects unprepared. They don't understand the trade-offs between IVF, HNSW, and Product Quantization. They pick the wrong similarity metric. They scale the wrong way.This book is the missing manual. It covers:The mathematics of embeddings and why they workHow to choose the right algorithm for your latency and accuracy constraintsDeep dives into Pinecone, Milvus, Weaviate, Qdrant, and ChromaBuilding production RAG systems that actually workIndustry case studies from Spotify to JPMorgan Chase20+ ready-to-run recipes for common scenarios

You know how to code, but everyone else seems to "just get it" while you secretly Google and ChatGPT everything. The Software Realm DECODED is the patient mentor conversation you've been searching for, Peter asks the questions you're afraid to ask, and the Ultra Senior Developer explains what bootcamps skip and seniors assume you know. By the final chapter, the imposter syndrome disappears and systems finally make sense.

"It’s 3 AM, your database just hit 500 connections, and everything has ground to a halt. Do you know why?"Most database outages aren't mysterious—they are architectural.
