Foundations of Production-Ready Development
Essential knowledge for vibe coders who want to build reliable, maintainable, and scalable services — without drowning in theory.
The more you build with AI, the wider the gap becomes between "code that works" and "code that lasts." A feature can run while the data model is fragile, costs explode, and changes become terrifying.
This section distills the development fundamentals that vibe coders and non-technical founders actually need. Instead of deep theory, you will learn the concepts and judgment calls that make a service reliable, maintainable, and scalable.
The 7-part map
Computer Science for Builders: Start with the Map
A practical orientation to the four neighborhoods of computer science: data structures, algorithms, system design, and development process.
Data Structures: The Containers Behind Fast Apps
Arrays, lists, hash maps, stacks, queues, trees, and graphs explained as practical containers for real apps.
Algorithms: Will Your Code Survive More Users?
Big O, binary search, and recursion explained as practical tools for predicting how code behaves as data grows.
System Design: The City Plan Behind Every Real App
Client/server, APIs, databases, caches, load balancers, queues, monoliths, microservices, and tradeoffs explained for builders.
Development Process: Git, Reviews, Tests, and CI/CD
The collaboration habits that keep software changeable: Git flow, pull requests, code review, testing, CI/CD, and technical debt.
A Complete Computer Science Roadmap for Builders
A practical computer science roadmap for builders: what to learn first, what to study next, what to skip, and how to turn the map into real projects.
Production Problems in AI-Built Apps
How to automatically catch common production problems in AI-built apps using monitoring, tracing, static analysis, and CI gates.
