Designing for social interaction

Bildkontakte is a social platform focused on helping people meet and connect.

As UX Designer, I worked across acquisition, mobile communication and social interaction mechanics, combining experimentation with interaction design across different parts of the product.

01Improving landing page conversion

The landing page was one of the most important acquisition touchpoints, with a strong focus on turning visitors into registered users.

I worked on different versions of the page and ran A/B tests across hero layouts, messaging and imagery to understand which combinations performed better.

Testing showed that images of people looking directly at the viewer performed better than more passive imagery.

That insight influenced how we approached visual direction on acquisition pages and reinforced an important lesson: seemingly small visual decisions can have a measurable effect on user behaviour.

Landing-page variants tested to compare hero imagery, messaging and layout.

02Rethinking profile picture ratings

Bildkontakte included a feature where users could rate profile pictures from 0 to 10.

The mechanic created engagement, but it also created a clear downside: people could receive low scores from complete strangers and see those ratings directly.

That meant a feature intended to be playful could easily become a source of frustration.

The challenge was to preserve the discovery and engagement value of the mechanic while reducing the feeling of being negatively judged.

I explored different models, including:

  • •smaller rating scales
  • •star-based systems
  • •positive-only interactions such as likes
  • •ranking highly rated profiles without explicitly exposing low-performing users to negative scores

How can a social mechanic create engagement without making the people being rated feel worse?

  1. 0–10
  2. Stars
  3. Likes
  4. Ranking

Team workshop mapping alternatives to the 0–10 rating: stars, likes and ranking.

03Designing chat as a core social experience

Chat was a central part of the Bildkontakte experience because it went beyond simple one-to-one messaging.

The product combined private conversations with public chatrooms, giving users a space to meet, talk and interact before deciding whether to connect more personally.

At a time when many dating products were becoming increasingly focused on profiles and photos, chatrooms gave Bildkontakte a more social and community-driven dimension.

The design challenge was to bring both modes together in a mobile experience that made it easy to move between discovering conversations, participating in group chats and continuing interactions privately.

I worked on the structure and interaction patterns of the chat experience, balancing immediacy with the need to keep different types of conversations understandable and accessible.

  1. Group chatrooms
  2. Private conversations

Mobile messaging: inbox, private conversations and empty states.

What changed

These projects covered very different parts of the product, but they shared the same underlying challenge: designing interactions that encouraged people to participate.

From improving acquisition, to supporting meaningful conversations, to reconsidering potentially negative engagement mechanics, the work pushed me to think beyond interface design and consider how product choices shape behaviour.

What I took from it

Bildkontakte gave me early experience in areas that continued throughout my career:

  • •using experimentation to inform product decisions
  • •designing interaction-heavy consumer products
  • •balancing engagement with user experience
  • •thinking about social mechanics from both sides of the interaction
