Cherifi
I build pipelines and data stories. I like working on crypto data — the speed, the transparency, the endless stream. Open datasets are the other side: public but rarely explored. The same instinct drives both: making opaque systems legible.
Projects
Tools I build and use — available for early access.
⚡ Radar
On-chain data stories, from signal to publish-ready format. Radar scans DeFi protocols, scores story potential, and generates a full récit scaffold — brief, narrative arc, charts — in one click.
