Hello! I'm Rose Hall

she/her • 🌎 Engineer • San Francisco (Wed 2:22 PM)

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.
