Story arc

How this shipped

Building the tools that build the toolsThree beats: what pressed against the work, how the stack answered, and what changed once it was live.

I · Constraint

The brief

Helping developers retain web development concepts long-term through scientifically-proven learning methods.

II · Build

The craft

Implemented FSRS (Free Spaced Repetition Scheduler) algorithm for optimal review timing. Combined flashcards with hands-on coding challenges.

III · Proof

What moved after launch

FSRS adaptive scheduling drives review timing based on individual recall. Covers React, TypeScript, and modern CSS. Combines flashcards with coding challenges so practice and recall reinforce each other.
