Learn Backend Development Free in 3 Months
Build server-side applications: version control with Git, database work with SQL, and REST APIs with Node.js.
Backend development is about what happens on the server: data, logic, and APIs. This three-month plan is 167 hours, about 1.8 hours a day, and it is the densest of the 3-month tracks. You start with Git and SQL because every backend job assumes both, then spend the bulk of the time in The Odin Project's Node.js path building real APIs and working with databases. This assumes you already know some JavaScript, since Node is JavaScript on the server.
The daily math
This plan is 167 hours of free courses spread across 90 days. That works out to about 1.9 hours a day, or roughly 13 hours a week if you prefer to batch it. Miss a day and you make it up on the weekend; the point is a pace you can actually keep.
The plan, course by course
Why this set, and what we left out
We chose Node.js as the backend language because it lets a JavaScript learner reuse what they know instead of starting a new language cold. We front-loaded three short SQL courses (Kaggle, Khan, CS50) rather than one long one so database skills build gradually before the heavy Node work begins. We left freeCodeCamp's 300-hour Back End certificate out; it is too large for three months and would crowd out the SQL grounding this plan depends on.
The honest catch
You should know basic JavaScript before starting, since Node is JavaScript on the server. And three months here covers building APIs and using databases, not deployment, scaling, or DevOps, which come with experience and separate tracks.

Frequently asked questions
Can I learn backend development in 3 months?
Yes, if you already know some JavaScript. Three months at about 1.8 hours a day covers Git, SQL, and building real APIs with Node.js.
Do I need front-end skills first?
You need basic JavaScript, which many people pick up front-end first. You do not need deep CSS or React knowledge to work on the backend.
Why Node.js and not Python for backend?
Node lets JavaScript learners stay in one language across front and back end. Python backend (Django, Flask) is a valid alternative if you came from the Python track instead.
