I run a profitable SaaS business all on my own.

Keeping it very simple: I push code to Github; then Capistrano (think bash script with some bells and whistles) deploys that code to the server and restarts systemd processes, namely Puma and Sidekiq.

The tech stack is fairly simple as well: Rails, SQLite, Sidekiq + Redis, and Caddy, all hosted on a single Hetzner dedicated server.

The only problem is that I can't deploy as often as I want because some Sidekiq jobs run for several days, and deploying code means disrupting those jobs. I try to schedule deployment times; even then, sometimes, I have to cut some jobs short.

Sounds like a use case for Cadence/Temporal-style fault-oblivious stateful execution with workflows. At last job, we did Unreal Engine deployments with pixel streaming at scale on a huge fleet of GPU servers, and the way we could persist execution state so hassle-free that the code would magically resume at the line right where it got interrupted was so astounding.

If you can, look into the `sidekiq-iteration` gem.
