What it is
A non profit offering free, interactive, browser based curricula across web development, data analysis, machine learning and more, each ending in a certification project.
Its real strength
Removing every excuse not to start. No cost, no signup friction, no local setup, immediate feedback. For someone unsure whether they even like programming, that matters far more than curriculum design.
Its limitation, stated honestly
Guided exercises in a browser build a false sense of competence, because the environment does the hard part. Use it to learn syntax and fundamentals, then move to something that makes you build unaided, such as The Odin Project or Full Stack Open. The certification projects are the part that pushes you there.
Best for: complete beginners, and anyone picking up a new language quickly.

Stuck on something specific?
Writing only gets you so far. If you want an answer to your situation rather than the general case, book a session and we will work through it together. Every session is free; a few slots open each week.
