Projects you'll complete
Bug Triage Lab
Diagnose and repair five broken functions, one bug type at a time.
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.
Score Tracker
Turn variables and types into a working score tracker used by a small games night app.
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.
Data Transformation Toolkit
Build a small library of pure functions that group, summarise, sort, and validate arrays of records -- the exact kind of utility code real apps use to shape data for dashboards, reports, and forms.
Algorithms & Data Structures Capstone
Bring together searching, stacks, hash maps, recursion, and graph traversal in five focused mini-implementations.
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.
