    Production-Ready App Upgrade

    Turn an existing application into a safer, production-ready system with one coordinated upgrade workflow. This bundle adds reliable error handling, observability, rate limiting, caching, background jobs, end-to-end tests, Docker packaging, and CI/CD automation. Use it when an app works locally but still lacks the safeguards, visibility, testing, and deployment foundations needed for real production traffic. Ideal for SaaS teams, APIs, internal tools, and growing web apps.
