I'm not talking about self-diagnosed high-velocity, I as their manager see that they are high-velocity, high-quality developers.
> That mindset may work for small shops or independent features but in my experience successful large products are built by people who are willing to invest as much effort in coordination as they do in heads-down coding.
I've always modeled my team's process on open source development, which has successfully produced very high quality "big" software. Documentation in code, PRs and issues, async communication... I've never seen regular company process (things like Agile) produce software that matches the quality of that done with a more distributed and async process.
From that perspective, hiring accomplished open source developers leads to an amazing team. Back to my original point, those people may be 18 years old or 60 years old. The trick is to build a team of people who have a proven ability to ship.
