Software tooling, automation, and graphics/compatibility engineering.

我目前開放自由接案,主要處理 Excel / VBA / Power Query / Python 自動化、資料整理與報表流程、Windows 小工具,以及既有程式的分析與除錯。

接案方向 / Freelance Focus

  • Excel VBA / Macro 自動化:批次匯入、欄位轉換、資料比對、報表產生、按鈕式操作流程
  • 多來源 Excel 資料整合:將不同客戶或不同格式的工作簿轉成統一資料結構
  • Power Query / Python 資料處理:清洗、轉換、彙總、驗證與例外紀錄
  • Forecast / Actual / Master Data 比對:依客戶、料號、月份等 Key 進行整合與差異分析
  • 工作流程自動化:把重複性的人工整理流程改成可重複執行的工具
  • Windows 小工具與技術問題排查:既有工具整合、測試、Debug 與效能分析
  • AI-assisted development:用 AI 加速原型、程式撰寫與測試,但以可驗證、可維護的交付結果為準

Excel 自動化的典型架構

不同來源 Excel
      ↓
Import / Mapping Layer
      ↓
Standardized Data
      ↓
Validation & Reconciliation
      ↓
Report / Dashboard / History

對於格式不一致的檔案,會優先採用 Mapping / Adapter 的方式處理,而不是把固定儲存格位置全部寫死,讓後續格式調整與新增客戶時比較容易維護。

可交付內容

依案件需求可包含:

  • 可直接操作的 .xlsm 工具
  • Power Query / VBA / Python 程式碼
  • 客戶 / 欄位 Mapping 設定
  • 匯入檢核與錯誤紀錄
  • 自動彙總與差異報表
  • 簡易按鈕、下拉選單與使用介面
  • 測試資料與操作說明
  • 後續格式調整與功能擴充

Public Projects

Synthetic manufacturing-data portfolio demo showing different customer forecast formats → standardized schema → baseline / actual comparison → dashboard / validation. Includes a downloadable Excel workbook, VBA adapter/reference source, mapping examples, and sample input files.

Browser-based local tool for comparing effective OBS Virtual Camera resolutions and browser-side rescaling behavior. Includes a complete local workflow, presets, launch scripts, and troubleshooting documentation.

Public engineering work around game graphics compatibility, frame-generation integration, DX11/DX12 paths, instrumentation, regression testing, and reproducible checkpoints.

Public engineering work related to HDR / rendering compatibility and integration testing alongside the graphics pipeline above.

工作方式

我偏好先用少量真實樣本確認資料結構與例外情況,再定義標準格式、驗收條件與可擴充方式。對企業內部工具,會特別注意:

  • 不讓使用者需要懂程式才能操作
  • 對缺欄位、日期格式、未知料號等異常提供清楚提示
  • 保留來源與更新日期,方便追查資料
  • 儘量避免難以維護的大量硬編碼
  • 先建立可驗證的 MVP,再逐步增加報表、歷史版本與 UI

Available for freelance automation / tooling projects.

若是 Excel、VBA、資料整理、報表自動化或小型工具案件,可以直接透過接案平台提供需求與樣本檔,再依實際資料評估工期與範圍。
