Team skills assessment tools

We have a widely distributed team through a few different acquisitions. I'm trying to get a feel for what competencies we have on our current team. Has anyone come across a tool that will gather data about all of the different languages/frameworks/tools and competencies for each of the staff? I want to make sure people don't leave out 'softer' skills for third party services like Zendesk, Twilio, Datadog, etc. Thinking of standing something like this up myself based on the type of skills assessment that job posting boards have for job seekers.

Thanks
