Master the skills engineers actually use.

Career roadmaps

Pick a goal — Quant Developer, ML Engineer, SWE — and get a dependency-ordered skill path, not a link dump.

Interactive coding

Real code, running in your browser. Lessons are mostly practice, not paragraphs.

A real skill graph

Languages, frameworks, CS fundamentals, and quant math connected by prerequisites — not equally-sized course tiles.

Projects

Apply what you learned in scoped, milestone-tracked builds instead of just isolated exercises.

AI tutor

A hint ladder that nudges instead of solving it for you — conceptual, then directional, then a partial fix.

Progress tracking

Spaced repetition and a transparent mastery formula — always labeled as a learning estimate.
