## Additional Note
I am partially employed by Integritee, Encointer and Ajuna. I did not receive
salary by them for the evidences that I stated above unless I state that explicitly. However, my polkadot/substrate expertise
is also growing by implementing tasks paid by ecosystem projects. Good examples are:

* Pioneering in implementing multiblock-migrations: [Bajun Parachain #43](https://github.com/ajuna-network/bajun-parachain/pull/43) & [Ajuna Pallets](https://github.com/ajuna-network/ajuna-pallets/pull/44)
* Implement Cross Chain Asset Transfer for Ajuna and Bajun: [Bajun Parachain #51](https://github.com/ajuna-network/bajun-parachain/pull/51/files) & [Ajuna Parachain #30](https://github.com/ajuna-network/ajuna-parachain/pull/30)
* Emergency Fix for the CheckMetadataHash signed extension for the encointer wallet [Encointer Wallet #1682](https://github.com/encointer/encointer-wallet-flutter/pull/1682)
* Implement & Pioneer in deploying Async Backing for Ajuna & Bajun
