I did a lot of hunt on LinkedIn with keywords like Terraform, Python and Puppet. I found that guy here. But years later, I have doubts about LinkedIn efficiency, as most good SWE I found through head hunters did not have the Python keyword on their profile even when they rock at it. Now I believe LinkedIn is only useful to target people who are good at self-marketing.
