Full-stack engineer who builds and ships AI-native tools end to end — Ruby on Rails, TypeScript and Cloudflare Workers.
🟢 Open to work · Chengdu, China (UTC+8) · On-site in Chengdu or remote Looking for: AI application engineer · Full-stack engineer · Developer tools / agent tooling
- I take products from idea to release on my own: data model, API, UI, deployment, docs, versioned releases.
- I focus on LLM applications: hybrid search (keyword + embeddings), MCP servers, scheduled AI workflows, BYOK clients and agent skills.
- I work agent-first. I write the spec, constraints and acceptance criteria; coding agents (Claude Code, Codex) write much of the code; I own architecture, review and quality.
- Background: 10 years in e-commerce systems — 4 as a backend engineer, 6 as a full-stack engineer — covering order and checkout flows, third-party system integrations and long-lived production services, mostly in Ruby on Rails.

Dong Xu（Dx），成都，全栈工程师，正在找工作。 我能一个人把 AI 应用从想法做到上线：数据模型、API、前端、部署、文档和版本发布。技术栈是 Ruby on Rails、TypeScript 和 Cloudflare Workers，重点在 LLM 应用：混合检索、MCP Server、定时 AI 工作流、BYOK 客户端和 Agent Skills。
10 年电商系统开发经验：4 年后端、6 年全栈，做过订单与结算等核心链路、第三方系统对接和长期维护的在产服务，技术底座主要是 Ruby on Rails。
- 求职方向：AI 应用工程师 / 全栈工程师 / 开发者工具，成都现场或远程
- 代表作：yaf（开源、可自部署的 flomo 平替，跑在 Cloudflare 免费额度上，自带语义搜索、AI 洞察和 MCP）、Vibe Hero（TypeScript 全栈 AI 开发转型指南，16 章，中英双语）
