I'm an independent software developer. At my day job, I work on the X-Plane flight simulator. Among other projects, I was responsible for the complete user interface rewrite for X-Plane 11, and for the massive multiplayer implementation (both client- and server-side).
I work primarily in C++ (for the simulator itself) and Elixir (for the massive multiplayer server), but a lot of the supporting infrastructure I work on is written in some mix of Python (for tooling), PHP (for our WordPress web sites), and Node.js (for our in-house Scenery Gateway web app).
On my own time, I develop the Unbound photo browser for Mac. This started as a "rescue" project—when I took over development, the app had a 1.6 star average on the Mac App Store. I've spent about a year fixing bugs, shipping new features, overhauling the marketing, and transitioning the Objective C codebase to Swift (and SwiftUI where appropriate).
