Hackaton testimonial from participant Chandraprakash Jha

Every minute with N3XTCODER at the 4th CASSINI Hackathon felt well spent! It was great to see our team go through several development phases so quickly. The event's framework provided many experts and mentors who helped us to develop our concept rapidly. Overall we all appreciated the guidance accessible for every step of the process. In the end, our team even won 1st place!

I'm happy to have been part of N3XTCODER's recent hackathon as a Jury member: surrounded by high-level participants, professionals, innovators and entrepreneurs, one can feel how technology can contribute to a more sustainable future. At the 4th CASSINI Hackathon, I found myself in numerous discussions about how space technology and data can enable #Greentech for banking and insurance services. Very enlightening!

About #Green4Europe

2022 has brought Ukraine and South East Europe into sharp focus. The challenges for the region run deeper than the current Russian invasion of Ukraine, and they extend far outside Ukraine’s borders. Already existing economic imbalances in Europe will be further exacerbated in the course of a green and digital transition that will fundamentally change the economies of European regions. 

Young creators in South Eastern Europe want to build a future beyond war, a future built on innovation, sustainability, and peace. We need to support young, innovative people and projects to regenerate their future.

In 2021, in the weeks before the invasion, the #Green4Europe Hackathon Series built a promising new network in Ukraine and Georgia of young innovators and creators, civic tech startups, and civil society who worked with German tech partners to seek out and develop the green tech projects to regenerate the region.

Despite the events of the past year, the #Green4Europe network is still strong. We redouble our efforts and build up this network further. Working again with the German Foreign Ministry and drawing on the #Alliance4Ukraine platform, from December 2022 to April 2023, we will find and support the most exciting new innovators and projects from Ukraine, Georgia, Germany, and Moldova.
