Hello, you're about to listen to a BBC podcast, so I'd like to tell you where you'll find more just like it.

I'm Izzy Lee Poulton, an assistant commissioner for BBC Sounds, which means I'm involved in the whole podcast making process.

Whether that's developing fresh formats or facilitating eye-catching artwork, I helped project manage all the details that make our podcast stand out.
