The product had been running on the web for some time before I joined. My primary contribution was net-new design of the mobile app version — designing the mobile UI/UX from scratch following the existing web design language — alongside redesign work on the live web product.

Three pieces of feature work stood out. First, newsfeed UX optimisation: I developed and implemented logic for newsfeed navigation to deliver relevant content quickly, supporting better engagement and retention. Second, trending keyword research: surfacing popular topics and posts at the right time so the community surface stayed alive. Third, cross-platform post display: optimising the rendering of different post formats — text, image — on the mobile app across iOS and Android so visual consistency and accessibility held up under varied content shapes.

The product reached a growth trajectory of around 15,000 sessions in 2024.
