Hello! I'm Rose Hall

any/all • Everything Engineer • New York City (Sat 7:48 AM)

Lifelong engineer, curious tinkerer, and unapologetic problem-solver. I thrive on unraveling complexity and building clever, often unconventional solutions. Whether it's code, circuits, or workflows. I don't just like thinking outside the box, I like to take it apart and see how it works.

Now

Recurse F2'25

The Recurse Center is a retreat for ambitious programmers. A mix of research lab, hacker dojo, and artist's residency - where you learn deeply, collaborate freely, and discover what's possible when play and focus collide.
