+Hi all,
+
+I would like to nominate myself to be the Karbor PTL for the Train cycle.
+
+I began to contribute to Karbor project since 2016, as a core reviewer from
+Queens cycle and serve as PTL in Stein. It's a completely different experience
+for this role and it's a big responsibility to continue to promote the
+development of the Karbor project.
+
+In Stein, due to the loss of contributors, our development pace has slowed
+down, but we also do a good job. We mainly focused on bug fixing and the
+optimization of cross-site backup and restore, and do a lot for improving the
+checkpoints management in different bank cases, added new API for doing
+checkpoint state reset. The unit test coverage and document has also been
+improved.
+
+For the next cycle, I think we will main focus on the following items:
+
+- Refactoring the bank concept. Support using database as a new bank driver, so
+  we can store the metadata in databases in specify cases
+- Support using RBD as a new bank
+- Continuous optimization the implementation of multiple nodes of
+  operation engine
+- Improve backup and recovery efficiency
+- Improve unit test coverage
+
+For Karbor, this is a special moment. We need focus on the project improvement
+to make Karbor better using and cover more use cases, so we can attract more
+developers from all over the world.
+
+I have working with Karbor for several cycles, and I have a deep understanding
+of the codebase and inner working of Karbor, so I am coming to nominate myself
+to be the Karbor PTL for Train cycle.
+
+I would be honored to have your vote.
+
+Thanks,
+Jiao Pengju (jiaopengju)
