The SWE Cheat Sheet Pack with CodeCrack

Your desk reference for security, backend and DevOps

30 one-page sheets with 266+ items. Every item explains how it works and gives you the fix, with the real command or code line you can copy. Not screenshots: crisp A4 pages with selectable text, made to print.

What's inside

• Security (13 sheets): web, API, auth, network, cloud, phishing and social engineering attacks with their fixes; database, server, web and cloud security rules; a security review checklist for pull requests
• Core concepts (9 sheets): Linux, networking, APIs, microservices, Docker, SQL, cloud, encryption and AI, each term explained with an example
• Mistakes & fixes (3 sheets): SQL, Linux and Kubernetes, with the corrected command or config

How engineers use it

• In code reviews: keep the security sheets and the checklist open.
• At your desk: pin the command references you look up every week.
