I design how products behave, moving between early ideas and mature systems to make experiences feel connected across products.

About Me

Jenna Ammerall holding Maeve, her dachshund, outdoors in Seattle Maeve, Jenna's dachshund, nosing a bright pink rose held out to her on a Seattle sidewalk Jenna standing on a granite outcrop above Seoul at dusk, the city skyline and N Seoul Tower behind her

Over nine years at Microsoft and Meta, I've worked across platform-scale products: from modernizing productivity tools for the web, to centering people around conversations and shared interests, to increasing product access for all.

I spend my time chasing after my dachshund, Maeve, and serving on the board of my condominium association, where I enjoy solving the long-term challenges of a small community.

Much of my creative energy comes from discovering new music and exploring art exhibitions. I love collecting ideas, moods, and perspectives that often become the backdrop for whatever season of life I'm in.

If something here
resonated, say hello.

I've been thinking about what happens as products become more autonomous. I'm interested in balancing what products decide with what people intend to do.
