We run VPS servers on DigitalOcean.
Usually wordpress and we have one website per VPS.
We are need someone who has skills with the LAMP and LEMP stacks, but if someone can help with building a custom stack as well, that would be great.
Our main concern is that the servers we have now have very long TTFB and we would like help to reduce that. Currently that can take as long as 2 seconds and we would like to see it more like 0.1 or less, including sites on full HTTPS.
We are open to talking about the options, but after whatever we do to our current servers is accomplished, we will want to know exactly how you did your work so we can replicate it into future servers.
