Software Development Foundations
Learn to think like a professional developer, not just write code: read an unfamiliar codebase and build a mental map of it, break down a fuzzy requirement into buildable pieces, and understand how code gets organized and why. This guide covers reasoning clearly about data, state, and edge cases before they blow up on you, turning an ambiguous "make it do X" into a spec with explicit questions and assumptions, and choosing between design alternatives knowing there's no right answer, only trade-offs. It also works through the feedback loop (edit, run, observe, adjust) as a discipline for making safe changes, and how to work on shared code as part of a team: code review, pull requests, and feedback. You work on Habitat, a real task-tracking app that a four-person team built fast and now has to maintain and grow; you come in as the new developer who didn't write that code and has to understand it. It closes with an end-to-end project: you receive a real request on Habitat and deliver it as a reviewable feature, applying the whole guide. It's the discipline that separates someone who "knows how to code" from someone who builds software other people can maintain.

Outcomes
What you'll be able to do
- Understand what makes a professional different: reading code is the real job, and the cost of software lives in change, not in writing it the first time
- Break down a fuzzy request into buildable pieces: single responsibility, naming as thinking, and the function as a unit of thought
- Recognize why code structure exists: modules and boundaries, layers, separation of concerns, and coupling and cohesion in plain words
- Reason clearly about data and flow: the shape of data, state (what changes and when), edge cases as first-class citizens, and making the invalid impossible
- Work the feedback loop as a discipline: edit-run-observe-adjust, reproducing before fixing, and small steps beating big leaps
- Turn an ambiguous request into a small spec: separate what was asked from what's needed, ask the right questions, and surface hidden assumptions
- Choose and document conscious trade-offs: simple vs flexible, speed vs robustness, "good enough," and reversible vs one-way decisions
- Build as a team on shared code: communicating through code, code review as a conversation, the pull request as a unit of change, and handing off and picking up work
Before you start
What you need to bring
It's for you if...
- Self-taught developers or bootcamp graduates who already know the basics but feel like they're missing the mental scaffolding others seem to have
- Junior developers who are about to join (or just joined) a team and will work on code they didn't write
- Programmers who master a language's syntax but not how to think about and organize real software
- Anyone who wants to move from "knows how to code" to "builds software other people can maintain"
Requirements and materials
- Basic programming knowledge in any language: variables, functions, conditionals, loops
- Having written at least one small program start to finish (the language doesn't matter)
- Not a course on your first language: it assumes you already know how to type code, and teaches how to think about it

Common questions
What people usually ask
No limit. It's a free guide: come in whenever you like, as often as you like.
No. Modules run from easier to harder, but you can jump to the one you need. Progress is saved per lesson.
Whatever is needed is listed under “What you need to bring”, above. If nothing is listed there, you can start from zero.
In the Club's WhatsApp group, and every two weeks there's a live with an instructor where questions get worked through.
Yes. It's issued automatically once you finish every lesson, with a verifiable code you can share on LinkedIn.
