Conversational Development With Claude Code — Part 11: Implementing Ratings in the Backend with Claude Code and Docker

Conversational Development With Claude Code — Part 11: Implementing Ratings in the Backend with Claude Code and Docker TL;DR We implemented the Ratings feature in the Platiflix backend using Claude Code v2 with Sonnet 4.5, fully inside Docker, orchestrated with a Makefile, accelerated using Dangerously Skip Permissions in a controlled environment, validated with 39 passing tests, and finalized with a structured security review aligned to OWASP. This is disciplined AI-assisted backend engineering — not autocomplete. When architecture stops being theory In the previous phase, we migrated the database. In this phase, we introduced behavior. A ratings table without services is inert. An endpoint without validation is fragile. A feature without tests is irresponsible. So the objective was precise: Implement the Service Layer Expose controlled endpoints Preserve container isolation Maintain test stability Perform a security audit before declaring success This is where planning becomes execut
