Bio
Coline Péquin
It was a pleasure to work with Sergio for 3 and a half years at Witco. He was always there to help all members of the product and development team. Sergio was, among others things, a reference for email and export management. He knew how to take a step back to understand the improvements to do. Sergio is a hard worker who loves to learn new things - always there to investigate an issue, even if it was not on his field of expertise. Very passionate about his work, he was always enthusiastic about working on a new project. Although we'd never met, we managed to create a relationship of trust and mutual support based on listening, empathy and conviviality! I highly recommend Sergio. It was a real pleasure to work with him, both professionally and personally. He would be a real asset to your team, so don't hesitate and choose him !! ☀️🥑
Ricardo Clavijo
I highly recommend Sergio . he demonstrated exceptional efficiency and proactivity, consistently exceeding expectations. But what really sets Sergio apart is their commitment to continuous learning, not just in technical skills but also in soft skills like communication and teamwork. I'm confident that Sergio would be a valuable asset to any team looking for someone who is not only skilled but also driven to constantly improve themselves and the team around them.
