Hello, I have a question before starting the soldering process, can you confirm me the diode is correctly oriented ?

Thank you !

    AFAIK orientation does not matter as long as it is consistent across the entire board. Double check with the PCB designer/manufacturer.

    Edit: Why exactly am I being downvoted? What I said is correct. Hope it helps somebody as adding one line to the firmware is trivial, especially as compared to re-soldering.

      While true, you would have to change the firmware to swap column and row polarity if you reverse all the diodes e.g. #define DIODE_DIRECTION ROW2COL in QMK. Conventionally, QMK assumes rows are on the cathode side of the diodes and drives the columns high. ROW2COL reverses that so that the rows are driven high and columns scanned instead.

      It’s best to stick to the convention so you avoid surprises.
