Alexandre took over code that many would have deemed irrecoverable, and he managed to bring it back to life with remarkable efficiency.
He worked quickly, cleanly, and with a real sense of priorities, which allowed us to launch our MVP in very good conditions and in record time.
Excellent technical level, clear and reliable communication! I recommend without hesitation.

Alexandre quickly resolved an issue in code that did not belong to him and that he had no prior knowledge of. This was done very quickly!
