Groysman's Minister of Finance and Zelensky's NSDC Secretary
A civil servant under four consecutive presidents: advisor to Prime Minister Yekhanurov (2005), freelance advisor to Yanukovych (2010), coordinator of the Reform Center under the Presidential Administration of Lyovochkin, deputy head of the Presidential Administration under Poroshenko, Minister of Finance (2016–2018), NSDC Secretary under Zelensky (2019). Upon appointment to the Ministry of Finance, he rebuffed accusations of offshore holdings: admitted having British companies but insisted on their legality and tax payments; explained involvement as "passive income from partnership." The General Prosecutor's Office, in the framework of a criminal case concerning Yanukovych's criminal organization, investigated the Coordination Center under the Presidential Administration where Danyliuk worked since 2010 — he is the sole common founder of two charitable organizations that emerged from that center.
Two dismissals due to conflicts and a fight at a birthday party
In 2018, dismissed from the Ministry of Finance after a public conflict with Groysman: accused the prime minister of stalling the DFS reform and sent a letter to G7 ambassadors alleging a corrupt lobby in the fiscal service. Left the NSDC four months after appointment due to a conflict with the Head of Office Bohdan, who tried to influence council decisions, and pressure from Kolomoisky regarding PrivatBank. In July 2021, at his own birthday party, struck former Minister of Economy Milovanov and asked him to leave the party and report his expulsion to Yermak.
