As a weather startup, we needed a guy that learned fast. And damned did he learn fast. He even learned to repair the coffee machine in one day once (after he broke it)
Julien
Ex-CTO of WeatherForce
Working with Guillaume was great, he was very attentive to customers and other colleagues alike. We even learned some hieroglyphs when we had to read his handwriting.
He wrote small reports of what he did every week. That was a pleasant surprise.
Marc Sourisseau
Team Leader at IFREMER
He showed up and had many ideas. Some good.
