I’m Henry Fellerhoff, a Chicago-based software developer and musician.

Currently, I lead development at Modern.fm and work on a variety of other projects. I’ve worked as a Software Development Intern at Dendron and participated in the MLH Externship.

I am most passionate about working on projects relating to music or economic and climate justice. I strive to create beautiful, maintainable, and impactful websites and applications.

I am available for both freelance and part-time web development positions. If you would like to talk more, get in touch!
