Hi,
my name is Matija and I have been running a validator on Centrifuge from July 2020 by the name Mile. Before starting on Centrifuge I was running a validator nodes on Amber for a few months, which was back then a requirement to get RAD tokens to start validating on Centrifuge.

I am also running a validators on Polkadot and Kusama (2 validators), where I am participating in the 1000 Kusama and 1000 Polkadot validator program. I am participating in democracy on Kusama and Polkadot and sometimes discussing the referendums and proposals in the Element chats.
If you need any additional questions, please write here or in the contact details below. I am also quite active in the Polkadot Element groups for both Kusama and Polkadot, so we can also chat there
