About
I make difficult information feel approachable.
I’m Maël, a frontend developer focused on the space between raw data and human decisions. I work with product teams that have outgrown generic interfaces and need a clearer way to reveal, navigate and act on complex information.
My role goes beyond implementation: I help shape the visual model, challenge interaction choices and build the frontend foundation that keeps the product useful as it grows.
