Public Transport app

3 months end-to-end to release

Applab created at the end of Ovi had a mission to release mobile apps related to mobility and location quickly. The first application was for the public transportation application, which complemented well the existing car navigation app. We were a self-contained team with one PO, one front-end, and one back-end developer, one user researcher, and one UX/UI designer myself.



In 3 months, we released the Symbian version of the app for the local partner, Berliner Verkehrsbetrieben (BVG) i.e., Berlin's public transport.
I created a substantial reference design document that was usable for 5 ~6 years .

Success factors

The team was composed of experienced people for each discipline.
The peers within the company are always open and collaborative to give their perspective.
There was a history of knowledge within the company to be repurposed.


End-to-end working collaboratively with the team and stakeholders.
From reference design to visual design handoff, I was productive to produce all the needed items for the release.
