a Senior Software Engineer with 17+ years of building software that solves real-world problems. I'm passionate about domain modularity, clean architecture, and crafting maintainable software in Ruby and Rust.
My source code now lives on aaronmallen.dev. My GitHub repositories will be mirrors of those hosted there. You can find my old GitHub source code in the GitHub archive.
Ruby and Rust, with strong experience in Rails, GraphQL, microservices, and domain-driven design. I'm a maintainer of Hanami, dry-rb, and rom-rb, and a big fan of everything in that ecosystem.
