# Member request
Hello everyone, I'm Branislav Kontur. I've been part of Parity since July 2022, where I began my journey as a member of both the Bridges team (now Bridges+XCM) and the System parachain team.
My primary goal was the development of the BridgeHub parachain runtimes, which facilitates message transfers between various global consensus chains (substrate), such as Rococo<>Westend and Polkadot<>Kusama.
I would like to join Polkadot's technical fellowship as a 1st dan member.
