About

Developer

I am a 33 year old developer with AuDHD. I started playing around with programming in the 5th grade, and never really stopped. I am passionate about building robust, maintainable systems, and while I primarily do backend development, I also sometimes value frontend work.

As of 2026 I am working in the Greenfield Packing Automation team, at the LEGO Group, as a Senior Software Engineer.
