I build practical, Windows-first tools and AI-assisted workflows with an emphasis on local-first design, clear boundaries, and verifiable releases.
我專注製作實用、Windows 優先的工具與 AI 協作流程，重視 本機優先、清楚邊界、可驗證交付。
Most projects start from a real workflow problem: reduce repetitive work, make advanced tooling easier to use, and ship something people can actually run.
多數專案都從實際工作流程中的痛點出發：減少重複操作、降低工具使用門檻，並把想法做成真正能執行的產品。
Batch-export books you legally own in Google Play Books: DRM-free EPUB/PDF files are downloaded directly, DRM-protected titles keep their official .acsm handoff for Adobe Digital Editions. HTTP-first, resumable, and local-first.
批次匯出自己合法擁有的 Google Play 圖書：無 DRM 書籍下載 EPUB/PDF，受 DRM 保護的書籍則保留官方 .acsm 交接流程。採 HTTP-first、可續傳、本機優先設計。

- Local-first desktop tools — Windows EXE, CLI, desktop GUI, portable workflows.
本機優先桌面工具 — Windows EXE、CLI、桌面 GUI、可攜式流程。 - Accessible AI workflows — bring AI into familiar interfaces instead of forcing users into new ones.
降低 AI 使用門檻 — 把 AI 放進熟悉的介面，而不是要求使用者重學一套工具。 - Automation for repetitive work — media, documents, downloads, data handling, and operational workflows.
重複工作自動化 — 媒體、文件、下載、資料處理與日常作業流程。 - AI-assisted development with verification — agents help build faster, but releases still need tests, packaging, and explicit limits.
有驗證的 AI 協作開發 — AI Agent 協助加速原型、重構與文件，但交付仍需測試、打包與清楚限制。
Earlier work includes Excel/VBA business automation, Palm and Android field applications, web-based submission/review systems, and internal operational tools. Private or organizational projects are described by capability only; identifying details and production data are intentionally omitted.
過往作品包含 Excel/VBA 營運自動化、Palm 與 Android 行動程式、線上填報／審查系統，以及組織內部作業工具。私人或組織型專案僅描述能力與成果，不公開可識別資訊與正式資料。
- Local-first by default — if it can run on the user's machine, avoid adding a hosted backend first.
- Release-oriented — downloadable, runnable, and verifiable beats a one-off demo.
- Privacy-aware — user files, images, and tokens should not be sent to unnecessary services.
- Clear boundaries — licensing, platform rules, unsupported scenarios, and operational risks should be explicit.
