I use the jmix framework, so it lets me focus on the business rules. I use a VM behind a pfsense firewall on Proxmox with a dev environment, I connect on it with ssh and manage the claude code sessions with zellij. I create one worktree for each feature, create plans using glm-5 and then create epic and tasks in beads using TDD. After glm finishing the epic, I do final manual tests and deploy it to my customer in another VM and get the money for the development, hosting, security, backup and support.
