A solo developer details how they engineered a safe production deployment system using multiple Claude Code sessions. Initially, these sessions, each working in a separate Git worktree, faced conflicts when attempting to merge their work simultaneously, leading to production failures and data integrity issues. The developer implemented a series of solutions, including a full test suite before publishing to the main branch, isolated PostgreSQL test databases, and a single sequential launcher for merge requests, effectively creating a merge train system. These changes mechanized the deployment process, preventing agents from interfering with each other and ensuring reliable production releases. AI
