About

Every commit lands on GitHub for you to fork & remix.

Romi Nur Ismanto is an engineer and author working at the intersection of agentic AI, network operations, and security. His path runs from designing one‑time‑password authentication systems in 2004, through two decades of banking‑grade security infrastructure and nationwide e‑channel monitoring, to building and training neural networks and autonomous AI agents today. He holds an M.Eng in Network Security from Universitas Indonesia and a B.Eng in Informatics from Universitas Gadjah Mada, has written six books and study guides, and has shipped thirty‑four projects — every one of them public on GitHub.

PdfRomeo macOS PDF toolkit thumbnail
Fig. 1 — PdfRomeo

No. IReleased: 26 July 2026

📄 PdfRomeo — 43-Tool PDF Suite for macOS

A professional PDF toolkit for Apple Silicon that keeps every document on the machine — no upload, no account, no cloud round-trip. Forty-three focused tools across six families: organize (merge, interleaved mix, split by range/bookmark/size/text, extract, reorder, crop, rotate, N-up), edit & sign (click a page to place text or click existing text to rewrite it, fillable form creation, signature images, watermarks, Bates numbering continuous across files), convert (PDF to Word, table-aware Excel, PowerPoint, text, and JPG/PNG/TIFF at any DPI), protect (AES-128 with granular permissions, unlock, flatten), and scan repair (real image-downscaling compression, auto-deskew, Tesseract OCR, damaged-file recovery). Built on PySide6 with pikepdf and PyMuPDF, its engine layer carries no Qt imports at all, so all forty-plus operations are drivable from a CLI, a server, or a test harness without ever opening a window.
