App & Portal Character "Ask Sid"

I’m looking for someone to design an original cartoon-based character called Sid to support an app and online portal.

Sid is an AI assistant that users can ask questions about their own data, providing insights, ideas and practical advice.
The character should be geeky, clever, funny, lovable and slightly quirky — someone users enjoy interacting with rather than a typical AI bot.
Initially, I’m looking for a designer who can create the character and personality of Sid, with the potential to develop different expressions, poses and animation later.
Please share examples of similar character work you have created.
