From Zero to Dev — A GitHub-Powered Self-Learning Roadmap

All resources are free, open-source, and hosted on GitHub. No paid courses needed. Every step includes: what to learn → which repo → how to start → what to build next.

---

Your Starting Point

You Already Know	Level
SQL	Beginner (SELECT, WHERE, GROUP BY, JOIN basics)
Python	Beginner (wrote a bot, used APIs)
JavaScript	Beginner (tinkered with a fuel-bot)
Git	Beginner (clone, push, token usage)
Termux	Mobile dev environment

---

Phase 0: Set Up Your Tools (Do This First)

0.1 Master Git

Why first? Every new thing you learn gets committed to a repo. Git IS your learning journal.

Step	Topic	Resource
1	Clone, add, commit, push	You already do this
2	Branch, merge, pull, rebase	git-tips — cheat sheet, ⭐12K
3	.gitignore templates	github/gitignore — official, ⭐165K
4	Git from the inside out	pluralsight/git-internals-pdf — free book
5	Oh Shit, Git!?!	ohshitgit — fix common disasters

0.2 Your Terminal (Termux)

pkg update && pkg upgrade -y
pkg install python nodejs git sqlite curl wget -y
pip install requests
npm install -g nodemon

0.3 Learn the Command Line

Resource	Stars	Why
the-art-of-command-line	⭐155K	One-page masterclass, English
explainshell.com	—	Paste any command, get line-by-line explanation

---

Phase 1: Algorithms — Learn 11 Languages at Once

hello-algo ⭐107K

Animated, interactive data structures & algorithms. Supports Python, C++, Java, C#, Go, Swift, JS, TS, Dart, Rust, C, Zig — all in one book.

How to use it (30-day plan):

Week	Chapter	What You Get
1	Arrays, Linked Lists, Stack, Queue	Foundation — compare syntax across 11 languages
2	Hash Table, Tree, Heap, Graph	Core data structures
3	Searching, Sorting, Divide & Conquer	Classic algorithms
4	Backtracking, DP, Greedy	Advanced thinking patterns

Pro tip: Read the Python version first (it's the simplest), then click "Switch Language" to see how the same algorithm looks in JS, Go, or Rust. This builds cross-language fluency faster than any tutorial.

Backup / Deeper Dive

Repo	Stars	Best For
TheAlgorithms/Python	⭐201K	Every algorithm implemented in Python
TheAlgorithms/JavaScript	⭐33K	Same, in JS
TheAlgorithms/Go	⭐16K	Same, in Go
CS-Notes	⭐179K	CS fundamentals, Chinese + English

---

Phase 2: Pick One Language & Go Deep

Based on your repos (Python bots + JS bots), you're already touching both. Pick Python as your primary language — it's the easiest to read, and you already have projects in it.

Python — Your Primary Language

Order	Resource	Stars	What You'll Learn
1	30-Days-Of-Python	⭐44K	Day-by-day, from print("hello") to APIs
2	wtfpython	⭐36K	Python quirks explained (learn what NOT to do)
3	python-patterns	⭐41K	Design patterns in Python
4	realpython/python-guide	⭐28K	Best practices, packaging, deployment
5	awesome-python	⭐237K	Curated list of libraries — your Python dictionary

JavaScript — Your Secondary Language

Order	Resource	Stars	What You'll Learn
1	javascript-algorithms	⭐191K	Algorithms in JS, with explanations
2	You-Dont-Know-JS	⭐182K	Deep JS concepts, book series
3	33-js-concepts	⭐65K	33 core concepts every JS dev should know
4	clean-code-javascript	⭐93K	Clean code principles for JS

SQL — Your Data Language

Order	Resource	Stars	What You'll Learn
1	SQL Tutorial (W3Schools)	—	Interactive, run SQL in browser
2	sql-murder-mystery	⭐17K	Learn SQL by solving a crime
3	SQL-for-Data-Analysis	—	Real-world queries
4	awesome-db-tools	⭐4K	Everything database tools

---

Phase 3: Build Real Projects (Where You Actually Learn)

project-based-learning ⭐216K

Build real things. Tutorials organized by language and difficulty.

Your path — projects that connect to your existing repos:

Your Repo	Project to Build	Language	Time
malaysia-fuel-bot	Build a Web Scraper	Python	1 weekend
malaysia-fuel-bot	Build a Twitter/X Bot	Python	1 day
my-malaysia-bot	Build a Chat Application	JavaScript	3 days
dbx-guide	Build a Database Engine	Python	2 weeks
notes	Build a Static Site Generator	Python	1 week

More Project Repos

Repo	Stars	Approach
build-your-own-x	⭐350K	Build your own DB, Git, OS, neural network
app-ideas	⭐82K	Tiered app ideas: Beginner → Advanced
realworld	⭐82K	Same app in 100+ frameworks
system-design-primer	⭐293K	Learn how big systems work

Phase 4: Your Roadmap Compass

developer-roadmap ⭐312K

Interactive roadmap charts. Click any node to see what to learn + resource links.

When to open it:

• Every Sunday: review where you are

• Before starting new topic: check if you have the foundation

Key roadmaps for you:

Roadmap	Why It Matters
Backend	Your bots are backend — learn the full ecosystem
Python	Aligned with your primary language
SQL	Your DBX and data skills
Git & GitHub	Your version control backbone
