Desktop App · Python, customtkinter, pynput · zachwh.com/lazyhand

Built as a privacy-focused alternative to free auto-clicker/macro tools that bundle ads, telemetry, or excessive permissions.

• Global Hotkeys: System-wide key listener supports up to 3-key combos to toggle actions or capture new bindings without focusing the app

Client-Side Web App · JavaScript, pdf-lib, JSZip · zachwh.com/awardfiller

Browser-based tool for filling out and printing military award certificates (AAM, ARCOM, MSM, Good Conduct Medal).

• Multi-Award Workflow: Slideshow-style editor for filling out multiple certificates in one session, with JSON save/load for both printer calibration and full award batches
• Print-Ready PDF Export: Client-side PDF generation with manual text justification and combined or per-award file output

• Rich-Text Editor: Bold, underline, links, lists, and pasted screenshots, all run through a server-side allowlist sanitizer, with images re-encoded to strip EXIF/GPS metadata
• Fillable PDF Generation: ReportLab builds a printable form with AcroForm fields that can be completed by hand or typed into in a browser or Acrobat
• Git-Backed Publishing: Each save renders static HTML and commits it to GitHub with per-user edit history and one-click undo
