I grew up taking things apart to see how they worked, and somewhere along the way I learned to enjoy putting them back together too. I've been building for the web since the 90s, when a personal site meant hand-written HTML and a lot of trial and error. Around 2008 I was designing GTK 2.0 themes for fun and posting them on Ubuntu Forums under the name Saint Angeles. That turned into roughly eight years of full-stack development, building sites and applications end to end, before the work pulled me toward the systems underneath them.
Now I'm a field tech at an MSP, handling networking, sysadmin work, and endpoint support. At home I run a Proxmox-based homelab with Home Assistant, OpenWrt, and whatever I'm currently pulling apart.
Most software today is bloated, tracks you, and drags in dependencies nobody asked for. I don't think you should need an account to use a tool. The projects I build are my answer to that: single executables, no telemetry, no subscriptions, no bullshit. If that sounds like your kind of software, check out KillerTools.net.
| Project | Description | Tech |
|---|---|---|
| KillerPDF | A full-featured PDF editor for Windows that installs normally or runs fully portable. Licensed under GPLv3 with no account required, no subscription, and no telemetry of any kind. | C# |
| KillerScan | A fast network scanner built for field techs that combines ARP and ping discovery, port probing, and active fingerprinting across HTTP, SSH, TLS, NetBIOS, and SNMP. Uses a weighted scoring system to classify devices and ships as a single portable executable with no dependencies. | C# |
| KillerFind | A fast file and content search tool for Windows that supports wildcard filename matching, line-by-line content search, and multiple search terms in a single pass. No indexing, no background services, no setup required. | C# |
| KillerNotes | An encrypted notepad for techs: instant full-text search, rich text with inline images and real tables, whole-database SQLCipher AES-256 encryption, and notes that tear off as shareable .knote files. Ships as a single signed portable executable. | C# |
| killer‑scripts | A growing collection of PowerShell scripts designed to make Windows computers actually behave the way you configure them, built for MSP field work and day-to-day endpoint management. | PowerShell |
| killer‑tools‑site | The source code for killertools.net, home of the Killer Tools suite. | TypeScript |
