For developers
Roadmaps, guides and small tools — the things we wanted while learning, made properly and given away. Free to use, no account required.
01 — Resources
1 available · more on the way
A concept-first path through data structures and algorithms. Learn one concept, solve a small curated set of problems, then move on — with progress that saves in your browser.
More soon
We add a resource here whenever we build something worth keeping — guides, reference sheets and small tools that come out of our own work.
02 — Why we publish these
We build software for a living, and we learn in public while we do it.
Anything that saved us time is worth handing on.
Free, with nothing to sign up for
Opinionated, so there is a clear path to follow
