Profile: https://flows.cv/sebastiansangervasi

Technical problems are easy, communication problems are hard. I'm that engineer who takes the time to understand what you're asking. I speak honestly about what I know and what I need to learn. And when I learn something I share it with others, through presentations, documentation, and hands-on help.
