A PERSONAL STUDY IN SOFTWARE ENGINEERING
THEENGINEER'SNOTEBOOK
This is a public notebook/wiki where I share what I learn as I study software engineering, hoping it helps others on the same path.
STATUS ✦ Actively studied
INTENTION ✦ Beneficial Knowledge
The Learning Paths
The Foundation
Start strong by understanding computers, the network, and the engineer's mindset.
Web Basics
Learn HTML and CSS, and build your first project to understand how the web works.
Programming Core
Master JavaScript, TypeScript, Git, and problem solving to become a real programmer.
Frontend
Build modern UIs with React, explore Vue and Svelte, manage state, and architect scalable systems.
Fullstack
Go fullstack with Next.js and Remix, server components, data fetching strategies and server actions.
Databases
Design, query, and scale databases using SQL, NoSQL, Redis, and modern ORMs.
Backend
Build production APIs, implement auth flows and handle real-time communication.
Testing
Write unit, integration, and E2E tests, then wire them into CI pipelines to ship with confidence.
DevOps
Containerize with Docker, automate with CI/CD, and deploy to the cloud using Terraform/Kubernetes.
Security
Secure your apps, understand networking deeply, and harden your production infrastructure.
Ecosystem
Extend your skills to mobile with React Native and desktop with Electron and Tauri.
System Design
Design scalable systems, optimize performance, and apply clean software architecture patterns.

Purpose & Stroy
The Messenger of Allah ﷺ said:
“When the human being dies, his deeds end except for three: ongoing charity, beneficial knowledge, or a righteous child who prays for him.”

This notebook/wiki is a humble effort to share beneficial knowledge. May Allah accept it.
The idea started during my university studies while preparing for exams. As I worked to truly understand my courses, I naturally started creating summaries, cheat sheets, and personal notes. I also used AI to simplify difficult concepts. Over time, this grew into a large and organized collection of knowledge.
At some point, I paused and reflected. I am a Muslim, and my religion encourages benefiting others. That moment changed my intention. Instead of keeping this work private, I decided to put in extra effort to refine it; editing, organizing, and simplifying everything so it could be useful and understandable for others.
With a renewed niyyah for the sake of Allah, and with the responsibility that comes with it; itqan (excellence) and ihsan (doing things well), this project became a way to document and share everything I learn throughout my journey in software engineering.
May Allah accept this work, place barakah in it, and grant us all tawfiq.
