How I shipped a production Go proxy using Claude Code without writing code directly

Short summary

A JS/TS developer shipped a production Go reverse proxy (ProxAI) for LLM API cost management without writing any code, directing Claude Code for every task. The workflow resembles being a hands-on tech lead: writing specs, reviewing output, testing manually, and directing corrections. Key insight: Claude handles what you spec — things you don't think to spec don't exist, so security reviews, responsive design, and edge cases require explicit direction.

• •Shipped a production Go reverse proxy for LLM API spending caps using only Claude Code
• •Workflow is active direction (specs, review, testing) not passive generation — first drafts were never shippable
• •Things you don't explicitly spec don't exist: security audits and responsive design required deliberate intervention
