Devon Bray

Boston-based Engineer with an educational background in Electrical & Computer Engineering, Computer Science and English Literature.

I seek out work which leverages interdisciplinary engineering processes. This is accomplished through my professional work as a Software Engineer, my freelance practice, and my body of open-source work published online.

The following is my portfolio, a selection of the best projects across the different areas I'm active. If you have questions please reach out via email.

Block The Wind

Block The Wind is a Maine-based art collective. Our goal is to inspire, fuel and exhibit creative works in New England. Between our annual festival and artist-first online store, we strive to introduce talented creatives, writers and musicians to the public. I am a founding contributor, leading every major project in the history of the organization. Check out the websites for the music festival and online store. Both the store and festival are on Instagram as well.
