Profile picture

Hi, I’m Nicolas. Pleased to meet you! 🧙🏻

I engineer automation so that we may focus on exciting challenges rather than repetitive and uninteresting frictions. My greatest disappointment is that it’s not automated yet, but it’ll happen eventually! 🤯

I believe in continuous improvement and open collaboration, doing my best to help wherever I can using a mix of technical and relational skills. I’m very good at breaking down complex systems/concepts and then synthesizing/communicating them.

I have assumed both crewmember and leadership positions, and most often both at the same time by sharing responsibilities within the team. I’ve been studying and working in international contexts for over 10 years and am convinced that diversity stimulates creative problem-solving. To me, the best team is made of autonomous individuals who know how to leverage each other: strong alone, stronger together 🤝
