Roadmap

Each step unlocks when the one before it is done.

  1. Programming Foundations

    Think like a programmer: values, logic, loops, functions and problem solving in JavaScript.

    ~14h17 lessons3 projectsbeginner

  2. Debugging Academy

    Locked

    Diagnose and fix syntax, logic, runtime, API and UI bugs like a professional.

    ~10h10 lessons2 projectsintermediate

  3. Version Control with Git

    Locked

    Learn Git from first principles: commits, branches, merges, remotes, pull requests, and how to undo mistakes safely.

    ~6h9 lessons1 projectbeginner

  4. Databases and SQL

    Learn how real applications store and query data: tables, SELECT, JOINs, aggregates, and how to design a simple schema.

    ~6h10 lessons1 projectbeginner

  5. Node Backend Foundations

    Locked

    Learn how servers actually work: requests, routing, REST APIs, middleware, databases, auth, and errors -- using plain Node.js concepts.

    ~12h10 lessons1 projectintermediate

  6. Algorithms & Data Structures

    Locked

    Think algorithmically: master arrays, Big-O, searching, sorting, stacks/queues, hash maps, recursion, trees and graphs.

    ~12h10 lessons1 projectintermediate

  7. Modern AI Engineering

    Build real, production-minded features on top of large language models: prompting, structured output, embeddings, retrieval, tool calling, evaluation, and shipping responsibly.

    ~10h10 lessons1 projectintermediate

  8. DevOps and Deployment

    Learn how real software gets from a developer's laptop to production: environments, secrets, containers, CI/CD, deployment, monitoring, and incident response.

  9. Projects you'll build

    • Score Tracker

      Turn variables and types into a working score tracker used by a small games night app.

    • Build a Grounded AI Assistant Pipeline

      Design and implement the core logic of a retrieval-augmented AI assistant: chunking, embeddings, retrieval, prompt assembly, and output validation.

    • From Laptop to Production

      Capstone: take a small app from local development to a deployed, monitored service with a working rollback plan.

    • Build a Validated, Authenticated REST API

      Design and build a small REST API with input validation, token-based auth, and consistent error handling.

    • Ship a Feature: Branch, PR, Conflict, Release

      Take a small project through the full real-world Git lifecycle: branch off main, open a pull request, resolve a merge conflict, and cut a tagged release.

    • Design and Query a Bookings Database

      Design a schema for a small bookings app (customers, services, staff, bookings) and write the SQL to query it.

    • Algorithms & Data Structures Capstone

      Bring together searching, stacks, hash maps, recursion, and graph traversal in five focused mini-implementations.

    • Bug Triage Lab

      Diagnose and repair five broken functions, one bug type at a time.

    • Number Guessing Engine

      Build the logic engine behind a guessing game using conditions and loops.

    • Ship the Analytics Bug-Fix Release

      Diagnose and fix a batch of realistic bugs in a small analytics utility library, then defend each fix with a written root-cause note.

    • Study Coach

      Final project: a study coach that summarises practice sessions and reports back in plain English.
