My experience

Many teams. One Facebook.

Each product team had its own goals and metrics, but people experienced one Facebook. I owned features within those teams and drove alignment toward decisions that served both the team and the wider product.

The work

Driving a product forward

My work spanned different teams and surfaces, but fell into two themes:

  1. 1
    GrowthHelping people reach and revisit Facebook.
  2. 2
    Consumer engagementKeeping Facebook’s social flywheel moving.

The experiences shown here are work I owned that were either publicly launched or tested.

Growth

Designing when and how Facebook should ask people to turn on notifications, log in, or visit the app from the open web.

01 · Reachability

Prompt people at contextual moments

I designed prompts for contextual moments to encourage people to turn on notifications so the Facebook app could reach them again.

02 · Off-platform entry

Turn off-platform video into an acquisition channel

For people arriving from outside the app, I designed a better logged-out video experience and app-entry moments. They could watch what brought them there, then choose whether to continue in the app.

Consumer engagement

Designing participation across live audio, birthdays, and feed while keeping each experience connected to the wider product.

03 · Live audio

Bring Live Audio Rooms to the web

As an intern on the listener experience, I helped bring Live Audio Rooms to the web by designing how people discovered a room and moved between full-screen, in-feed, and minimized listening. Because timing and state were central, I used interactive prototypes instead of static screens. The web experience launched publicly in the U.S. in 2021.

04 · Birthdays

Expand how people celebrate birthdays on Facebook

I owned the design for Facebook Birthdays and added features across notifications, feed, profiles, and creation. The work included ways to celebrate before the day arrived, personalize the moment, and respond afterward.

Social context moving from discovery before consumption, to social proof during consumption, to participation after consumption

05 · Feed

Use social context to make recommendations relevant

Among other work on Feed, I focused on social context and proof, signals that helped people understand why the content they discovered was relevant.

How I worked

Build alignment around clear product decisions and principles

Communicate the decision

I used PRDs, working sessions, reviews, and prototypes to make the problem, rationale, and interaction concrete. I chose the artifact based on the decision and audience, using my judgment to give the team what it needed to decide and move.

Root the rationale in principles

When I brought work to partner teams, I grounded the rationale in shared principles. When teams brought work to me, I evaluated it against my team’s principles and domain knowledge, then used that context to ask sharper questions and guide the decision.

Reflection

What I learned

Find the overlap between user value and team goals

I learned to look for the overlap between a team’s goals and a real user need. That was where ideas could genuinely resonate with people and reinforce the metrics the team cared about.

Break the work down and sequence it

At large scale, progress depended on breaking ambiguous work into decisions the team could test, learn from, and sequence. PRDs and prototypes made each step concrete.
