Good evening.
I am ready to discuss the details of our collaboration. Write to me. Thank you.

Hello!

I have real experience with Ubuntu/NGINX, Let’s Encrypt via acme.sh, bash automation, and cron (setting up/debugging auto-updates, mass virtual hosts, working with logs). I have done similar tasks for servers with a large number of domains.

Time estimate: 1–2 days for auditing the current scheme, fixing scripts, cron, running through domains, and testing auto-updates + updating documentation.

Working with limited SSH/sudo access is fine, this is standard practice. I am ready to start immediately after access and current documentation are provided.

Regarding the budget: I can take on the work within $250–350 (or we can discuss after a brief audit).
