What I
Built.
Products I shipped solo — from idea to App Store, from prompt to production.
My working loop.
These are the three tools I use most. I usually start in Notion, writing the project overview, engineering notes, and build plan. Once the shape is clear, I move the work into Claude Code or Codex and turn the document into something executable.
Querya
一款每天向你提一个问题的 iOS 应用——旨在训练「先思考再回答」的习惯。独立上架 App Store：从 SwiftUI 开发、UI/UX 设计、LLM API 接入到 Prompt Engineering，全流程由我一人完成。用户不多，但通过这个项目我完整学会了从零构建并发布一款原生应用的全链路。
What I Learned
Set2Study
一个能将任何学习资料转换为题目（选择题、多选题、填空题、判断题）、闪卡和考试的网站。通过这个项目，我学会了 LLM 输出格式的调教与解析、支付链路的接入，以及线上网站的运维。
What I Learned
InvestorResearch Skill
在黑客马拉松中构建的 Agent Skill——接入你的 Agent 后，它能像金融分析师一样思考。拉取市场数据、进行多维度分析，并在前端页面上可视化呈现。探索智能体编排与垂直领域专业能力的结合。
GitHub Repo north_eastAgent Skill
赋予任何 Agent 进行专业级投资研究与分析的能力。
Super Intelligence Office
A local-first multi-agent chat app built for fun. Six AI agents — a VC, a journalist, a scientist, a macro analyst, a philosopher, and a cat — sit in a room and discuss whatever topic you throw at them. Think Twitter, but everyone is brilliant (and one of them is a cat). Runs 100% on your machine with your own API key.
