Our team

Kevin Loaec

CEO

Technologist but not a dev, adversarial thinker who thinks everything is broken. Believes freedom of the individual is paramount.

Antoine Poinsot

CTO

Bitcoin contributor who loves advanced scripts but not broken ones. Wants to become a Greek philosopher when he retires.

Edouard Paris

Senior DEV

Was into Go, now is into Rust. Kinda like Mario, his goal is to exterminate all mushrooms.

Maria Monteiro

Operations Coordinator

She gets all the things done at Wizardsardine, is our shadowy super not-a-coder.
