What we've done - it's how we learn!

Boston University

Boston University

Full UX process, UI and React website

Using our process to create a more advanced, content-heavy website meant thinking in high-level, usable systems rather than products.

Harnessing the power of design thinking to create a streamlined information architecture, combined with a cutting-edge React + Gatsby tech stack, we migrated millions of pieces of content and delivered a workable Wordpress-based platform.
