Tools I wrote because I needed them.

Android app for annotating facade photos with dimension lines and free-form text boxes. Exports to JPG or vector PDF and shares straight from the phone.

Open source tool that turns a KiCad/Eagle PDF or image into the file you need to expose a presensitized PCB on an Anycubic Photon Mono or any other MSLA printer. No UVtools, no fuss.

Windows imposition software for print and prepress: n-up, booklets, step & repeat, tiling, variable data printing and numbered tickets, marks, bleed, ICC profiles and preflight. Opens multi-GB PDFs and saves 100% vector.

Windows app with a built-in browser that spots video on any page. Downloads YouTube, HLS, RTSP, RTMP and WebRTC streams, transcribes with Whisper and translates with NLLB-200, all on your own machine. Includes an MCP server.

GPU-accelerated RAR password cracker with custom CUDA kernels. 68 KH/s on RAR 5, 83 KH/s on RAR 3 and 6.69 MH/s on RAR 1.5 on an RTX 4060 Ti. Six attack modes, an interactive GUI and checkpoints to resume sessions.

Portable 46 KB executable to analyze and free up space in the Windows Component Store (WinSxS). 4 official DISM operations, 8 advanced methods and a bilingual EN/ES UI. No installation, no runtime.

MCP server that connects Claude Code to the B4A (Basic4Android) IDE: 31 tools to build, debug, design layouts and install APKs just by talking to it. No Java, no Kotlin, no Android Studio.

Portable ~3 MB Windows tool that turns text, URLs and vCard contact cards into QR code PNGs. Native Win32 interface written in Go — no Electron, no runtime — plus a CLI mode for batch generation from PowerShell or CMD.

MCP server with 62 tools connecting Claude Code to Microsoft Access. Build databases, forms, tables, queries and VBA code just by talking to it in plain English. For anyone with zero programming background who wants a real management app.

A PowerShell script that opens a WinForms window to list, add, edit and delete Hyper-V Extended ACL firewall rules on virtual adapters, no command-line wrestling required. The GUI Windows Server never bothered to ship.

An 8086 assembly library from 1996 that lets QuickBasic 4.5 send and receive packets over IPX, the LAN protocol before TCP/IP took over. Written by a 17-year-old with two coax-linked PCs and too much free time.

Windows service written in C# and .NET 8 that watches live TCP connections and firewalls any IP that isn't on your whitelist and touches a critical port like RDP's 3389. No database, no third-party agents, no complications.

A step-by-step tutorial to build a custom IIS HTTP module in VB.NET that blocks XMLRPC abuse, login brute force and attack patterns before they ever reach WordPress, with a second layer of defence in Windows Firewall backed by SQL Server.

A .NET desktop app to browse and edit ChromaDB knowledge bases with no Python and no server needed. Built as an internal tool for an AI agent that translated natural-language questions into SQL queries against a client's ERP.

A TCP/IP networking FAQ hand-typed on a monochrome 486/66 in November 1997, translated with every joke intact: IP, DNS, TCP, ICMP, UDP and more X-DDDDDDDD per square inch than the whole of RFC 791.

A 1996 attempt in 386 assembly to reconstruct scrambled Canal+ images by sorting shuffled video lines with a minimum-error algorithm. Canal+ was Spain's analog pay-TV channel. Spoiler: it sort of worked.

Second chapter of a 1996 x86 assembly tutorial written for a BBS: DB/DW data directives, logic gates, conditional jumps and the CPU flags register, with the original TASM examples. Whisky-ware, as it was.

x86 assembly tutorial I wrote at 15 for a BBS. Data types, registers, memory, the stack and interrupts. Whisky-ware, zero corrections, zero censorship — exactly as it was distributed in 1996.
