From Vibe Coder to Software Engineer

Stop guessing AI prompts and start building like a professional software engineer!

In Part 1: Foundations (Days 1–10) of the From Vibe Coder to Software Engineer series, follow the transformational journey of Leo—a non-technical professional who transitions from blindly copying AI prompts to mastering true computer science fundamentals.

Whether you use Cursor, ChatGPT, GitHub Copilot, or Claude, AI can write syntax—but only you can architect production systems. This 10-day intensive guide breaks down complex engineering concepts into crisp visual diagrams, mental models, and real-world production incident case studies.

• Day 1: How Software Really Works — CPU registers, RAM memory hierarchy, and process execution.
• Day 2: The Internet & The Web — DNS lookups, TCP handshakes, TLS 1.3 encryption, and global CDNs.
• Day 3: Memory Allocation — Call Stack vs Heap memory, reference pointers, and avoiding memory leaks.
• Day 4: Concurrency & Event Loop — Non-blocking asynchronous execution and unfreezing single-threaded web UIs.
• Day 5: Data Structures — Array vs Hash Map vs Binary Tree memory layouts and $O(1)$ lookups.
• Day 6: Big-O Algorithmic Complexity — Linear, logarithmic, and quadratic growth curves.
• Day 7: Version Control & Git DAG — Commit trees, rebasing, reflogs, and recovering lost production code.
• Day 8: Programming Paradigms — Object-Oriented vs Functional pure functions with zero side-effects.
• Day 9: Browser Rendering — DOM/CSSOM trees, layout reflows, and smooth 60 FPS repaints.
• Day 10: Modern Frontend Architecture — Next.js App Router, React Server Components, and client hydration.

Packed with 10 full-page technical blueprint infographics, practical code snippets, and real-world tech disaster case studies (like the Fastly global CDN outage and the Ariane 5 rocket disaster), this guide gives you the foundation to build software with confidence.
