*This referendum is to add and promote Tsvetomir to I Dan. Here's his application below:*

Hello!
My name is Tsvetomir Dimitrov (https://github.com/tdimitrov). I've been part of the Parachains core team since February 2022. My notable contributions are:

* Runtime API versioning: https://github.com/paritytech/substrate/pull/11779
* Conditional compilation support for `impl_runtime_apis` macro: https://github.com/paritytech/substrate/pull/14709
* I worked on various optimisations/fixes for disputes protocol. The work was under the heavy guidance of [@eskimor](https://collectives.polkassembly.io/user/eskimor). A few notable examples:
    * Disputes import prioritisation: 
        * https://github.com/paritytech/polkadot/pull/5336
        * https://github.com/paritytech/polkadot/pull/5567
        * https://github.com/paritytech/polkadot/pull/6275
        * https://github.com/paritytech/polkadot/pull/6294
    * Refactor dispute-coordinator, approval-voting and dispute-distribution subsystems to use `RuntimeInfo` instead of `RollingSessionInfo`:
        * https://github.com/paritytech/polkadot/pull/6968
        * https://github.com/paritytech/polkadot/pull/6993
        * https://github.com/paritytech/polkadot/pull/7123
* I've also participated in the debugging of a Kusama incident described in https://forum.polkadot.network/t/stalled-parachains-on-kusama-post-mortem/3998

I want to apply for 1st dan.
