tptacek is a security researcher and principal at fly.io [0]. And as an outsider looking in, seems to have been the eng behind some of their defining features [1]:
- udp support
- container2vm overhaul
- private networks aka 6pn
- some key flyctl (cli) commands like flyctl ssh, flyctl proxy
- metrics
- litefs
- perhaps, the imminent overhaul of the orchestration layer (?)
I don't want to come off as downplaying others engs at Fly (esp those from Compose.io) [0], but I wanted to point out how there's a marked difference between the period from when you joined them and years preceding that. A catalyst?
Of course, I claim no inside knowledge, so I may very well be mistaken (:
