Hi, I’m Joseph Koski — a software engineer with a focus on functional programming, AI, real-time, and safety-critical systems.

When I’m not coding, you’ll find me biking, hiking, fly-fishing, or spending time with friends and family.

I’m the author of Advanced Functional Programming with Elixir, published by Pragmatic Bookshelf, and the creator of Funx, a library of functional programming patterns for Elixir. The book and library complement each other: the book provides the structured learning path, and Funx offers the tested, documented abstractions you can use in your own projects.
