Mobility Hackathon 2018
My most recent hackathon. I participated with the team of professional and experienced developers to present an app for planning guided tours in Hamburg using public transportation. Unfortunately, the repository is private but you can check project presentation and video below.
Design the Smart Mobility – ITS Hackathon Hamburg
The following hackathon was organized by Deutsche Bahn (the national railway company of Germany). During this time, Telegram messenger was rapidly growing and introduced a convenient API for chat bots. As a result we decided to develop a companion bot for DB customers. Routing was implemented by integration with DB-API. Afterwards, we implemented additional functionality such as break and incident notifications on DB trains, and a couple of entertainment features.
Mobility Hackathon 2017
The first hackathon i participated in was organized by Hamburg public transport company (HVV). Our team tried to make a prototype for underground navigating without Internet connection. We used Bluetooth beacons for spatial orientation and presented an easy to use app for interaction with the users.
