ideastone — digital workshop of Pinyen Cheng
我是 Pinyen，獨立做軟體開發。你可以找我處理前端、後端、AI 串接、自動化、資料儀表板，或一個一直無法部署的專案。我會先把範圍說清楚，再開始做。
I’m Pinyen, an independent software developer. I help with frontend, backend, AI integration, automation, data dashboards, and projects that refuse to deploy. We define the scope clearly before work begins.

我實際做過的東西。
Things I have actually built.
這裡保留全部作品，不只挑最好看的幾個。每一件都代表我曾經把一個想法拆成需求、寫成程式，再想辦法讓它真的運作。
This is the complete portfolio, not just the most polished pieces. Each project represents taking an idea apart, building it, and making it work.
01
AI agent · MCP · Safety
LHIC — Local Human Intent Controller
為電腦操作型 AI Agent 加上一層本地控制：理解使用者意圖、檢查政策、要求人工批准，並在執行後留下可追蹤紀錄。這個專案的重點不是讓 Agent 做更多，而是讓人能真正控制它。

簡單一點，事情比較容易做完。
Keep it simple so the work gets finished.
01
你先說目前的狀況
Tell me the current situation
不用先寫完整規格。網址、錯誤畫面、期限和你希望的結果就很有幫助。

02
我整理範圍與風險
I clarify scope and risk
我會說明能做什麼、暫時不做什麼、需要多久，以及用什麼方式驗收。
I explain what will be done, what will wait, how long it takes, and how we will verify it.

開始做，過程保持透明
Build with visible progress
用短更新、測試網址或畫面回報，不讓專案突然消失幾天。

依原本說好的內容驗收，再把程式碼、權限和必要文件交給你。
We verify the agreed result, then hand over code, access, and essential documentation.

Pinyen Cheng
我住在台灣，喜歡把複雜的技術做成真正有人能使用的東西。比起只做一個漂亮畫面，我更在意它能不能部署、資料會不會出錯、下一個人能不能接手。
I’m based in Taiwan and enjoy turning complex technology into things people can actually use. More than a polished screen, I care whether it deploys, whether the data is reliable, and whether someone else can maintain it.
我的作品橫跨法律科技、資料儀表板、私有雲、部署工具、AI Agent 與一般 Web 產品。合作時你會直接和我溝通，不需要經過業務或多層轉述。
My work spans legal technology, dashboards, private cloud, deployment tools, AI agents, and general web products. You communicate with me directly, without sales layers.
