Hi, I’m Justine

Product & Interaction Designer. Prototyper.

Five years at Microsoft designing Outlook features building systems that make enterprise email feel human. From crafting core reading pane interactions to architecting AI-driven contextual chat, my work scales to hundreds of millions of users. I build functional, live-data prototypes to cut through ambiguity and guide complex visions into shipped products.

How I work

01

Lead with visuals

Using early, functional prototypes built with AI to rally PMs and eng around building the right thing, not just the easy thing.

02

Designing with the door open

Bringing cross functional partners into messy middle early because designing in a silo feels claustrophobic.

03

The last 5%

Craft is king. In a world of feature-first roadmaps, I love being on teams that champion visual polish that makes a product feel intentional.

A preview of my playground

Some of my most beloved prototype explores, the ones that never shipped, decisions I was proud of, and other fun things I’ve crafted over the years that didn’t make it into a case study.

Read with me. Challenged the idea that AI should only summarize, showing how guided, evidence-backed reading could transform understanding in Outlook.

Inbox groups. Reimagined first-run email triage around people rather than messages, testing whether sender-based organization could make crowded inboxes feel immediately approachable.

Immersive search. Tackled one of Outlook’s biggest customer pain points by blending search and AI, automatically surfacing answers alongside the emails that supported them.

Selection insights. Explored how Outlook could proactively identify areas worth investigating, using lightweight prompts to kick off richer Copilot conversations.

Guided reading focus. Explored a future where Outlook proactively surfaced personalized opportunities for action, helping users focus on what mattered and move work forward with Copilot.

Video messages. Explored how video could bring presence and nuance to email, challenging conventions around asynchronous communication years before video-first workflows became mainstream.

design

It's hard to imagine a time when I wasn't designing, but believe it or not, there was a time when I was dead set on becoming a concert pianist (haha yes you heard that right). It was all I knew growing up, I went to UCLA to pursue my degree in Piano Performance, but it didn't work out.

It was initially difficult for me to reconcile how drastic the career transition seemed, but I've actually come to find more similarities in the two than differences. I've always been an expressive person, which is why I chose piano, and that hasn't changed. Design, to me, shows up in many different ways. On the surface, it's pushing pixels in Figma.

But beyond the cliche fluff we often hear, design is the ability to convey an idea visually (which I think is the coolest superpower). Being intentional about the craft I put out into the world. Caring about and catering to a group of people. Making good choices. Holding strong opinions but loosely at the same time.

Come to think of it, I very rarely come across designers who have always known this was their life track. I think that's what makes this so special. Guess it was a blessing in disguise piano didn't work out 😉

Crafted with ♡ with Copilot + Figma MCP.
Thanks for stopping by, you rock.
