I'm Casey Kerr, a senior full-stack engineer who builds with AI as a first-class tool. Day-to-day I architect, ship, and maintain web and mobile applications in React, Node, and AWS. Right now I'm integrating LLM features into customer-facing portals for various enterprise clients through my consulting practice, Kerrsoft.
Before any of that, I was the kid who wouldn't leave the high school computer lab. I learned QuickBASIC at Watertown High, then taught myself C from books, and built my first video game with the AV club doing the art. Junior year I wrote a multiplayer QuickBASIC game called Stick Fighter that got so popular it overloaded the Novell network and got me banned from the school computers. The administration, deciding my energy needed direction more than punishment, designed a co-op summer job for me at Polymath. I didn't own a computer of my own until sophomore year, when I picked up a TRS-80 and a VIC-20 at a rummage sale. Most of my non-software curiosity went into radio-controlled cars and homemade robotics, which mostly meant cannibalizing home stereos (including my dad's favorite) and dragging the neighborhood's discarded electronics home to take apart and rebuild.
I got here the long way. Apple Industrial Machine Service first, building automated factory equipment and programming the PLCs that ran it. A few years at Signicast next, automating foundry assembly lines that replaced thirty operators with four. Then GE Medical, calibrating MRI and PET scanners. Then a zigzag through enterprise Java, AngularJS, and Magento, before landing on React + Node + AWS in the mid-2010s. The through-line is the same one I'm working on now: take a tangled system and make it boringly reliable, with no more abstraction than the problem actually needs. Complexity embedded in simplicity.
Off the clock, I still build indie games as a hobby. The four I shipped (plus plenty more prototyped) all date from my Endboss era, which wrapped up several years ago. I also help run the Waukesha Makerspace, a 501(c)(3) nonprofit I helped found in 2019. The makerspace is the thing I'm most quietly proud of: CNC shop, 3D printing lab, wood shop, electronics bench, and a community that didn't exist before we built it.
Consulting with Kerrsoft, helping companies integrate AI into in-house and customer-facing tools. Running the Waukesha Makerspace. Building an async correspondence-style RPG on the side. Drafting hard sci-fi horror.
Easily expose business logic to React components. Generate a provider and context effortlessly, simplifying access to controller hooks for streamlined development.
An Arduino-based arcade game using addressable LEDs and buttons — a color-matching shooter built for the Waukesha Makerspace.
An asynchronous correspondence-style RPG platform inspired by play-by-mail games — private turns, asymmetric information, AI-assisted narrative synthesis, slow play.
A configurable TTRPG character creation platform with full lifecycle management (create, level, manage characters across game systems) and a package-based extensibility model.
A shipped, live personal dashboard and kanban board built on Next.js 16 with AWS Cognito authentication — daily-driver tooling deployed under the caseykerr.dev domain.
A privacy-first foot-traffic counter for conference and craft-fair booths — edge face detection + embedding vectors, no cloud, no image storage.
A 3D puzzle/tile game published on the iPhone App Store (later delisted; no longer maintained).
A proof-of-concept avatar framework intended as the shared foundation for other titles — similar in spirit to Nintendo's Mii system.
A Tron-style grid-based tower defense shoot-'em-up prototype exploring hybrid genre mechanics.
A Tony Hawk-style rollerblading mobile game published on iOS for the Valo product line under ThemGoods Inc. (later delisted; no longer maintained).
A Next.js 16 personal portfolio site deployed to GitHub Pages, surfacing project work and writing under caseykerr.dev.
A working replica of the Hitchhiker's Guide to the Galaxy clamshell book prop from the 2005 film — animated screen + electronics in a 3D-printed shell.
A multi-app monorepo (Hono API, React web client, Expo mobile client, MySQL/Drizzle) replacing a legacy DSHA student enrollment and course-management platform — built primarily through AI with human-reviewed architecture and code.
An LED cube hardware project with addressable-LED pattern control.
An Arduino-controlled WS2812B LED marquee for the Waukesha Makerspace's retro arcade cabinet, with potentiometer + button mode controls.
An npm-published React utility providing an ApiService abstraction for defining service classes around HTTP APIs.
A cross-platform contact-capturing utility that pulled contact information from clipboards, web pages, and other sources — released across multiple Broadlook platforms.
A voxel-based sandbox multiplayer game design (Minecraft / No Man's Sky-inspired) on Unity 2022 LTS with Fish-Networking and a Node/Postgres/Cassandra backend.
A hard science-fiction horror book series set in the Sol system circa 2130, opening with "The Chronos Incident" — a prion outbreak spreading through a station network.
