Hazel's PC-98 inspired header: Hi, I'm Hazel! .NET developer, AI engineer and open-source maker. Building things and proving they work.

Portfolio ยท Engineering blog ยท LinkedIn ยท Email

Support me on Ko-fi

I'm Hazel (she/they), a Texas-based full-stack developer in C#, .NET and Angular. I make small, local-first apps that each do one job, and AI tooling I can prove works. A good tool should be reliable, approachable and a little bit cozy.ย โ™ก

๐Ÿงธ apps i've shipped โ€งโ‚Šหš

๐Ÿ’พ XIV Vault
Moves your Dalamud setup to a new PC: plugin settings, HUD, hotbars, keybinds and macros. Every backup is hash-checked, and every restore takes a safety backup first.

๐Ÿ’ฐ Gil Sweep
Answers "what should I farm for gil right now?" from market demand, competition, price trends and node timers on your world.

๐Ÿก Prompuff
Keeps the prompts that worked, with tags, versions and {{variables}}, and hands them to your agents over MCP. No account, no cloud.

๐Ÿงน Sweepling
Finds the dev servers and watchers your Claude Code sessions left running on Windows, and closes them only after you say so.

๐Ÿ”€ PR Sweep
Shows where your team's pull requests are stuck this sprint, across a whole GitHub org, with no labels to maintain.

๐Ÿ—บ๏ธ ConAtlas TX
Puts every anime con in Texas on one calm page, with dates checked against each organizer's own site.

๐Ÿพ Staypaw
Puts your keyboard focus back when another app steals it, and holds the keys you press meanwhile so the stealer never gets them. Nothing injected, no telemetry.

Apparently, my response to a minor inconvenience is to build an entire app about it.

๐Ÿค– ai engineering, proven โ€งโ‚Šหš

๐ŸŽฎ sdl3-porter
Ports SDL2 code to SDL3 and catches the bugs that still compile. Each of its 17 traps is proven by a fixture in CI, and Haiku 4.5 went from 0.39 to 0.92 with it. How I proved it

๐Ÿงช Axiomarium
Tests your AI coding setup like software: agents, skills, hooks and evals, plus axm, a CLI that checks them.

  • ๐Ÿฐ Shybun mutes your mic and camera in every Windows app with one key. Its badge says you're muted only when Windows confirms it.
  • ๐Ÿงพ Tattlehop keeps a receipt of what your coding agents changed on your PC outside the repo, and undoes it once you say so. Nothing leaves your PC.
  • ๐Ÿท๏ธ Carmine Workbench swaps the tokens, cookies and API keys in curl commands, headers and logs for labels before you share them, so the debugging detail stays. Nothing you paste leaves your PC.
  • ๐Ÿชก Mendmoth shows your sticker on every background, fills the see-through gaps that dark mode gives away, and exports it for every place you post. Nothing leaves your browser.
  • ๐Ÿ’ฅ Oopsling turns a crash in your .NET app into a GitHub issue the user files from their own browser. The app itself sends nothing.
  • ๐ŸŽจ Wippup turns the Krita or Procreate file you already saved into a vertical reel of the piece coming together, for the times you didn't record. Nothing leaves your browser.
