Software engineer · Applied AI · Game dev at heart

Corey King

I build software people rely on, and AI that shows its work.

For seven years I built training software for the U.S. Air Force in C# and Unity. Now I'm building AI tools that find real answers instead of guessing, and writing about what I learn along the way.

Guild Wars 2 Achievement Helper

An AI companion I built to plan my Guild Wars 2 sessions and decide what to do each day. It reads my account through the GW2 API, including items across my bank and every character plus achievement progress, and grounds every answer in real game data.

TodayDaily lockouts, Wizard's Vault, and time-gated crafts with a live reset timer.
GoalsLegendary crafts, with materials counted across storage, bank, and every character.
ProjectsAchievement trees with notes the AI writes once and saves for next time.
Closest to doneEvery unfinished achievement, ranked by percent complete.
Ask the PrioryA chat agent in the voice of a Durmand Priory scholar that turns answers into trackable cards.

How it stays honest: the model never does the math. Agent tools calculate progress in C# and hand back sorted facts, and my API key stays on the server.

A little about me

I'm a software engineer who has spent most of my career in C# and Unity, building training software the U.S. Air Force relies on. I've always been a builder at heart: I studied game development at Columbia College Chicago, co-founded an indie studio, and still design my own games.

These days I'm focused on AI that people can trust. My Guild Wars 2 helper started because I wanted a straight answer about my own account, and it turned into the best lesson I've had in grounding AI in real data.

Off the clock you'll find me on a golf course, deep in Guild Wars 2, or planning the next trip. I grew up living in a lot of places, and seeing how other people live shapes how I design for them.
