Estonian and Ukranian tech partnership dates back to 2016 when Estonia helped Ukraine to pave the way for the architecture of digital government. Today, the collaboration is stronger than before, and, what's more significant, Estonia is learning from Ukraine by using the state app Diia as a base of mRiik. We discussed the strong tech collaboration between the two countries with Estonia's CIO Luukas Ilves, the project manager of mRiik Nikolai Kornõšev and Mstyslav Banik, the head of the eServices development in the Ministry of Digital Transformation of Ukraine.
